Hi I have a rover and I coldn’t use the temperature sensor because I dont undestand the value that it send. I had read that I have to calibrate that but I dont know how to do it.

I posted a quick write-up here on how to read the values:

Hi JocKrlos22,

Welcome to the RobotShop Forum. The temperature sensor on V1 and V1.5 of the DFRobotShop Rover is the LM35 from National Semiconductor. The original intended use was to play around with the analog signals and get respective values, but if you want to convert those into Celcius or Farenheit, you’ll need to read through the LM35 datasheet. It’s not the easiest to understand, and if we come across a formula which does it, we would be happy to post it here.

Hope this helps,
