THUM

Temperature Humidity USB Monitor

Simple Reliable Temperature Humidity Monitoring

The THUM is a true USB device to monitor temperature and relative humidity of interior living, working, and storage spaces. The THUM is ideal for server rooms, warehouses, kiosks, manufacturing areas - wherever accurate and reliable temperature and humidity monitoring is required.

Do you Need to know the current temperature and humidity in a particular area?
Do you Need immediate notification if the environmental conditions go beyond specific limits?
Do you Need a log of all temperature/humidity/dew point readings for further analysis?
Do you Need a visual graph of ongoing environmental conditions?
Do you Need the ability to view this information via the Internet?
Do you Need all of this to be easy to install and setup?

Then you Need a THUM !

The USB interface makes this sensor easy to install. The included software runs under Windows 2000, XP, Vista, Win 7, Win 8, Win 10, 2003 Server, 2008 server, 2012 Server, 2016 server, 32 & 64 bit. The software monitors the temperature and humidity, storing the readings to an Access or Microsoft SQL server database. The software can send e-mail if an alarm point is reached to notify you of environment problems in the monitored area. The software can also generate graphs of the data or export the data to several different file formats so you can do your own analysis of the data. The program also generates html pages that can be automatically saved to your web server in order to provide world wide access to the current temperature and relative humidity data.

We had a build project that we maintained an environment of 68 degrees F +/-(3) with 45% humidity, +/- (10%) for an extended period of time. The THUM gave us the information that we needed and it was readily available through the PC that we were using on the project.

We have built a sealed enclosure for a server that is in a highly dusty environment and are using the THUM to monitor the internal temperature of the enclosure. The enclosure is air conditioned and if the air conditioner were to stop and a THUM alarm be generated, the server goes thru an orderly shutdown. The THUM has been very easy to use and performed as advertised.

I run a small ISO17025 Accredited calibration lab and I am using your THUM with our Fluke 5520A/SC1100 multi-product calibrator to comply with the requirements of ISO17025. Thanks for a great product.

We use it to monitor the temperature in our laboratory and imaging rooms and are thinking about using it for our server rooms. We log this to our database, so our customers can look at the temperature during their study on the study web page.

I just wanted to give you some "kudos" for your quick service. I ordered my THUM Temp/Humidity sensor on Saturday and I already have it! It took me less than 15 minutes to set up, including configuring the Web access and email notifications. This is a great little product!! Thank you so much.

I got the THUM to work in under ten minutes after opening the box! I am using Ubuntu 9.10. The installation worked without problems. Very nice product.
