Room Temperature Monitoring

Dear All,
I need to develope a room temperature monitoring system which will alert by send mails when the temperature goes high. I just wanted to know whether there is any such hardware in the market, together with java, I can acheive this. Any help will be greatly appretiated. Thanks in advance. You can also mail me to [email protected] Thanks once again.
Ramya.

ramya1us,
Have a look at http://www.ibutton.com/ibuttons/thermochron.html and at http://ibutton.com.ibuttons/java.html . They seem to sell plenty of hardware and information on writing software to interface with it.
I know of someone who has bought some of their hardrware and created a user controllable WebCam with it.
Hope this helps.

Temperature Monitor Alert:Memory controller heatsink Results!!!

Hello all...
I have a question about the Memory Controller Heatsink sensor in the temparature monitor and I would appreciate it if you could shed any light in my problem.
Well it was long time since I checked my temperatures on my G5 DP 2.3 so yesterday while I was into some MP3 encoding I heard the fans making alot of noise ,not something unbearable but not the usual silence behaviour I was used to even under heavy load and with the nap off.
So because of that noise I decide to check it with the temperature monitor but nothing unusual came up except...yes you guess it the Memory Controller heatsink.
An alert came up and inform me that the temp was over 75 C/167 F.
The threshold was by default at 75 C/167 F.
Let me add that it's summer here and a hot one at 37 C and the room is not airconditioning,but it was exactly the same one year ago(June 2005)and I never came up with an alert.
Also I have no problem with the rest indications.
So what do you think is it normal or may I have a broken fan?
And finally what is the Memory Controller Heatsink?
Thanx in advance!

The memory controller heatsink is shown, with the associated cooling tubes and fins, in the right-hand photo of the 'back' of the main logic board here
http://homepage.mac.com/jerrycube/jerrycubepix/22601bluebord.jpg
Air is pulled over the back of the main logic board and through the cooling fins, by the fan in a plastic housing, at 90deg to all the other fans, behind the hard drives.
This fan is called "Main Logic Board Backside" by Hardware Monitor in this ancient DP2.0 - and is showing "20%" in 22deg C room temperature. "Memory Controller Heatsink" is at 54deg C.
37deg C is above the specified max. 'Operating Temperature' of 35deg C shown here
http://support.apple.com/specs/powermac/PowerMac_G5_Late2005.html
I think it would probably be advisable to find some way of lowering the temperature of the room the G5 is in...

No sensors for Temperature monitor on the beige?

Hi,
I just tryed to installed Temperature monitor on my beige, and it reports that there is not sensors it can find on the system. Is it normal on the beige?
Thanks

Steve,
some other pieces of software ... used if you overclock your CPU or install a ZIF upgrade.
You should know that a ZIF upgrade with a G4 does report a CPU temperature with these programs, but that it is inaccurate (putting it mildly). Mine reads below room temperature. This is a feature of the G4 implementation, I was told.
I have a simple Radio Shack temperature monitor, a small probe on a one meter wire to an LCD readout. The probe wedges neatly into the heatsink, and can be shielded from cooling fan air with a small piece of foam. The wire can be lead out through the speaker area on the MT.
This probe picks up the difference in heatsink temp caused by toggling the cache on and off. It also shows that Sys 9 runs hotter than OS X, 48 C vs 42 C (varies with external temp. of course, here 26). Heavy Photoshop use will raise the OS X reading several degrees, but never to the level of Sys 9.
It also changes with its placement in the heatsink, and also with heatsink spring position. On time I didn't get the spring on right and saw a higher temp than expected so I could correct it. Also, my installation also has two small 12v fans (wired in series off the 12v disk drive supply so they run quieter) that considerably increase airflow over the CPU.

Wait Until Room Temperature Before Turning On?

Hello this is really something I have never considered since my Apple Cinema display is my first LCD monitor. I know this should apply to all LCD's but I am really just curious. If an LCD monitor has been outside in the cold (in my case just got delivered) and it is pretty cold from being in transport is it neccesary to wait until it comes down to room temperature before turning it on? I heard this is good practice with crt monitors but not sure about lcd's.
I am waiting anyway just incase but just wondering any opinions on the matter...
Thanks

thank you for the response it is helpful. While the monitor didn't have any condensation on it and I finally turned it on. I got impatient and waited for a few hours but it felt warm to touch (although I didn't open it up and feel the insides:)). I could imagine this is something to be careful about if you get a new monitor and it is winter time..your all anxious/excited and you could perhaps do some damage. I do wonder though if it really could do anything? I read somewhere in my search that the freezing point in "Liquid Crystal" is quite low but I guess there are other compnents to consider too... ok I am just going on and on now...
Thanks

My iPad mini won't work at room temperature. I have to warm it up in my hands/arms for 2-3 minutes before the screen works correctly. Anyone else have this issue or know a solution?

Two or three weeks ago, I had a cracked screen replaced on my iPad Mini 2 with retina display (32G). It worked perfectly for 2-3 weeks, so I don't know how relevant the screen repair is. Anyway, the iPad is currently running iOS 8.1.3. I completely reset it because I want to sell it, but recently, the screen display started to have issues. One afternoon I turned it on and the screen was a faint gray with vertical streaks that went away after I turned it off then back on. That night, the screen would stay black when I tried to turn it on. It was a different black to being off, though. When I try to turn it on it changes to a brighter black, if that makes sense. I can see a change in the shade of black, but there's no color or app icons. The sound works even when the screen doesn't. The only way I can get it to turn on properly is if I hold it in my hands/arms for 2-3 minutes. I think the heat from my hands has something to do with it. It's just weird that regular room temperature seems to be too cold. We've had a cold winter in NY this year and my iPad may have spent 1-2 hours in my cold car the day this happened, but I can't say for sure. Has anyone else heard of this issue or does anyone have a solution?

I Also have this problem!!
In my situation, the screen simply started exhibiting the same symptoms a few weeks ago (early February) for no apparent reason. At first I thought the screen was dead, but discovered the heat solution by accident. Now I turn it on and keep it from going to sleep until I go to bed. Thank goodness the battery is still awesome on this thing.
I bought it new and still has the original screen, I keep it at home (never below 62 degrees). Coincidentally, this happened a day or two after the expiration of the warranty!! Any help figuring this one out would be eternally appreciated.

Is it possible to transfer the temperature readings through "Serial I/O" port of Lakeshore temperature monitor?

With this monitor, you can have 2 analog outputs that you can transfer to the computer by using DAQ boards. In my case, I need temperature measurements at 3 different locations so I need 3 analog outputs, which is not possible with this device.
However, the monitor can also store temperature data in its memory and print the data. What I need is not to print the data but send the data to the computer somehow in digital form and postprocess it. I am using the "serial I/O" port to connect the device to the computer. I think I can do some configurations on the temperature monitor with the drivers in the link (http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD... ) but I am not sure if the device recognize the commands that I send through the I/O port.
Any advice on how to transfer (in digital form) the stored data on the monitor to the computer?

http://sine.ni.com/apps/utf8/niid_web_display.download_page?p_id_guid=0241DD1B3AAF0341E0440003BA7CCD...
and the temperature monitor is the one in this link: http://www.lakeshore.com/products/cryogenic-temperature-monitors/model-218/Pages/Overview.aspx
Actually, it says in the manual that the stored data can be send to either printer or they can be retrieved by the computer interface. However, there is not enough information about how to perform this task.
I am using labview to read the data for the analog outputs and the drivers in the first link are also in labview language. But with those drivers, I cannot retrieve the data to the computer.
I will check MAX to test the communication with the device, though. Thanks for the advice!

Good Temperature Monitor for C2D MBP??

Just got my 17" MBP and it's great!!
I am new to the laptop world, so if someone can recommend a temperature monitor (preferably free) that would be great.
It seems fine, but I'd like to be able to monitor this.
Cheers

It may actually be overkill......
But this is the best one I have found:

Temperature Monitor for OS 10.3.9

I need an application or console command that will show me the temperature of my CPU.
I'm running a Beige G3 that is using a G4 processor. It's running OS 10.3.9 through the use of the application xPostFacto. I've found the apps "Temperature Monitor 4.8" and "Hardware Monitor 4.8," but those don't support any Mac OSs below 10.4.x. Temperature Monitor 4.7 supports Mac OS 10.3.9, but I can't find a download of it for the life of me. All of the links redirect to version 4.8.
Please, any help would be much appreciated, my project is at a stand still until I can find something that works.
Thanks!

Click on my TMM name at left & send me an email. I'll send you the 10.3 version. Don't know if your Mac has the sensors to monitor the temps.

Temperature monitor lite

temperature monitor lite has detected the SMART sensor on my 1.83 mbp... can anyone tell me what temperature range is "normal" for my machine?
thanks in advance.
MacBook Pro Mac OS X (10.4.6)

i know the whole heat thing has been done to death, but i was still hoping somone would humor me. i couldn't find a "normal" range listed in any other thread, or i wouldn't have posted.
and actually, sadly, my mbp isn't running just fine. among other issues, when it runs hot, my fan spins up and then down right away... i know, i know... the infamous "moo" has also been done to death. but before i send my machine away for service for two weeks (two weeks! an eternity) i thought a comparison with other users' experiences would be prudent...
anyone?

New MacPro: Good temperature Monitor Application for the nMP?

Can anyone suggest a good temperature monitoring application they have used for the new Mac Pro?
Thanks

I would recommend iStat Menus (http://bjango.com/mac/istatmenus/). I switched to it when I got the Mac Pro 2013 because Hardware Monitor doesn't work with the new Mac Pro. It's pretty good, although the history is only visual with graphs showing the evolution of the different sensors temperature. With Harware Monitor it was possible to read the temperature that were recorded at a certain point in time.

Best Temperature Monitoring Program?

Hey all, first time posting in the forums.
I recently got a mid-2012 MBP for college, so of course I immediately began putting games like Borderlands and GTA:SA on it. It runs anything I throw at it beautifully, but it gets awfully hot while it does. I know this is common for MBP's, even up to 90 degrees celsius, but it is something a tad worrisome when it gets over 80 (some games get it there every time....). So I've been trying to monitor it to at least be sure I'm not letting it get up there too often or for too long.
So had a few questions about temperature monitoring with Macs. I've currently got 3 programs running monitor temperature and system usage- System Pal, iStat Pro, and SMCfancontrol (which I also kick up a bit when playing the more GPU intensive games). The problem is that all three show different temperatures. Right now SystemPal reads 41 degrees celsius, SMCfancontrol reads 49, and iStat Pro has temps between 30 and 42 degrees. Which one's right? Is there a more accurate/definitive program for temp monitoring?
If it makes any difference, I usually play projected onto a 32 in LG TV using a thunderbolt to HDMI. I know this is more GPU intensive to begin with, but after going HD it feels a necessary evil.
If anyone happens to know of ways to keep temps down while gaming, monitor temps during full screen apps/games, or ways to monitor GPU usage (right now I have none ) I'd greatly appreciate advice on that too!
Thanks so much for answers!

Try iStat Menus 4.02 or Temperature Monitor 4.96 or Hardware Monitor 4.96.

CPU temperature monitoring utility - It works!!!

After long seeking and testing many HW monitoring programs it works! CPU temp monitoring on toshiba notebooks! Hmonitor v4.2.5.1 at http://hmonitor.com/
Good luck!

Hi sauliaus
Thanks for your information.
I have checked some postings and it seems that some user would like to install the temperature monitoring utility.
I'm sure this post will help many users.
Thanks again ;)

Internal temperature monitoring utility?

Is there any monitoring software (similar to Activity Monitor) that detects whether key components such as the CPU and hard-drive are running at a reasonable temperature or are overheating?
I believe that temperature-monitoring sensors are present inside the casing so in theory what I am asking about should be possible.

Hi, KDS-KDS. My experience has been that temperature-reporting utilities such as the one linked by roam above (which I've tested) are only able to find a single sensor in my Tibook, the same generation as yours. That sensor watches only the hard drive, which is normally one of the cooler parts of a Tibook. Though there clearly are additional sensors in the machine, it appears that their output is unavailable to (or perhaps isn't readable by) such reporting software, for some reason. Owners of other Mac models have reported quite varied results, from highly satisfactory (several sensors detected) to no sensors detected at all.
This question came up several times in the Tibook discussion forums a while back, and my recollection is that no Tibook owner, regardless of which of the four generations his machine belonged to, ever found any temp-reporting software that could provide a readout on the CPU. If you do find one, please post in over there and let us know.

1130AG temperature monitoring (SNMP / MIB)

Hi
Im trying to get some SNMP monitoring running for multiple 1130AG APs. I keep running into walls though. APS are running with the following image : c1130-k9w7-mx.124-25d.JA1.
Problem 1.
I cant use the show environment cmd on the APs. According to the following official Cisco document, the show environment cmd is supported from image version 12.2(11) JA , but is not available on my APs running 12.4(25d)JA1:
http://www.csd.uoc.gr/~hy435/material/cr12425d.pdf
Problem 2.
According to the Cisco IOS MIB locator, the 1130AG AP does not support the ENVMON-MIB . That MIB is generally used for temperatur monitoring on many cisco devices. The 1130AG does however support ENTITY-MIB , but I am not entirely sure that this MIB can return temp info. There is very little/no documentation on this.
Can anyone help me out? I would very much appreciate it :)

Temperature monitoring for Core i3 CPUs

I have a i3 330M and lm-sensors results in nothing. Any ideas?

I've dug up some more info..
For temperature monitoring, a QST SDK is needed for supporting the ICH8 southbridge. The OpenAMT project is working on that (http://www.openamt.org/), but there doesn't seem to be much progess.
However, it looks like Intel will be releasing an SDK itself. See: http://software.intel.com/en-us/forums/ … hp?t=54851
Maybe after that we will have temperature & voltage monitoring support for all Nehalem and Arrandale chipsets.
