Rated 5 out of 5 by from Exactly what was needed! We have had this unit installed and working with a MS Access database that reads the Temp / RH on a timer and prints it on the calibration certificate. Working perfectly so far!

Rated 4 out of 5 by from Easy Temp/Humidity Logging I bought this temperature/humidity probe for our physical testing lab and attached it to the USB port of a PC attached to a test instrument running in lab ambient conditions. The probe was easy to install after downloading Omega's software and logs our testing conditions but I had to get help running the software. Omega's data logging team was able to help.

Rated 5 out of 5 by from Great product for awesome price! just bought this product a week ago and couldn't be more pleased. The usb and software makes using this device so easy and just requires downloading the software. The data is very very easy to copy and paste to excel. The software's plotting program is not the best but is good for a quick view of whats going on. 100% would recommend and I already thinking about how I can buy more sensors from omega... seriously so easy to use.

do you have examples of using the telnet commands in visual basic? I have VB code that reads USB via Rs232 converter and want to automate a process. Do you have example code not using telnet?

Is this require to be calibrated annually?

Asked by: JAM1991
Performance of the sensor can vary depending on frequency of use, application and storage conditions, so there is no simple answer to your question. Calibration requirements are based on your company procedures. Some companies require equipment to be calibrated annually. Others are comfortable with calibration only when the item readings are drifting from the specs.

Hi, I like to incorporate this device into a system that's controlled by a set python code. Do you have the class to communicate and commands to read temperature and humidity? Thanks, John

How can I connect my own software to the sensor? Do you provide a list of commands that can be sent via Serial communication?

Asked by: bart30332
You would need to use this software to have it work with the computer: ftp://ftp.omega.com/public/DASGroup/products/RH-USB/TRH%20Central_1.3.17.0721_online.zip If you want to use the telnet commands, here is the list: ftp://ftp.omega.com/public/DASGroup/products/RH-USB/RH_USB%20Command%20Reference.pdf Thank you for your question.
