AHT10 Temperature & Humidity Sensor. ... I’m happy I got the AHT10 sensor module and Arduino Uno working together. I never expected it to work without problems! There are still some mysteries, I agree ...

Nice method and analysis. The temp sensor 3 pin devices are simple and cheap but good for 0.5 deg C precision or nearly a full degree in human measure.

The microcontroller-based concept was chosen because I wanted to scale the sensor system later to suit other applications. Here is the diagram of my Arduino infrared close proximity sensor. As you can ...
