Sensor Ozono mq131

20190219· Question about Ozone Gas Sensor 12Bit (MQ131) measurement. More than 400 PPM of ozone from my product. Arduino Uno + Arduino Uno Compatible I2C Shield + Ozone Gas Sensor 12Bit (MQ131) Connect the power for 3 days and heat the sensor. The wrong amount of ozone is measured. As the amount of ozone increases, the measured value of MQ131 decreases.

20210506· How do I convert bits value shown in serial monitor to ppm? I need help with code.

This breakout for the MQ131 sensor responds to the presence of ozone in the air. As the ozone concentration increases, the resistance changes and the ozone concentration can be measured by measuring the analogue output voltage. The sensor is of good precision and is normally used in ozone concentration detectors. There is a 3362 potentiometer on the board with which the digital signal ...

According to the picture, the sensor is a Winsen MQ131 low concentration (black bakelite version). You can have additional information on the sensor in the datasheet. Your sensor is mounted on a PCB with some features like converting values (analog to digital), controlling the heater, maybe providing I2C bus...
