To calibrate the sensor for the environment you’ll be using it in, Hydrogen click has a small potentiometer that allows you to adjust the load resistance of the sensor circuit. For precise calibration, the sensor needs to preheat (once powered up, it takes over 24h to reach the right temperature). Hydrogen click communicates with the target board through AN (OUT) mikroBUS line. It’s designed to use a 5V power supply only.
