Ozone 2 click - board with an MQ131 sensor for O3 ...

Ozone 2 click is an Ozone detection (O 3) sensor, based on the MQ131 gas gas sensor has a sensitive layer made of SnO 2, which changes its resistance when exposed to sensor is able to sense O 3 concentration in the range of 10 ppm to 1000 ppm. The Click board™ is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ131 sensor.

Arduino - Calibration

This example demonstrates one techinque for calibrating sensor input. The board takes sensor readings for five seconds during the startup, and tracks the highest and lowest values it gets. These sensor readings during the first five seconds of the sketch execution define the minimum and maximum of expected values for the readings taken during the loop. Hardware Required. Arduino or Genuino ...
