Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Attached is photo of my sensor comparison screen. It shows that the HDC1080, TMP107 and BMP180 track closely for temperature measurement. The DHT22 and DS18B20 are the least accurate temperature sensors.

An interesting test there Rogersan - and so easy with an MM and TFT to do.

Just out of interest, is the average that you have displayed meant to be the average of all the individual temps? If so then it is a bit high (being only 0.1C below the highest individual temp. Pointing this out in case you have a 'bug' in your code.

Also, the Plat RT - is that a bit low too? I am assuming all sensors are running simultaneously and measuring at the same 'point' (as close as practically possible)!

Great stuff . . .
