MQ131 Ozone sensor measurement - Software - Community

· I recently bought Arduino Uno Compatible I2C Shield + MQ131 Ozone Gas Sensor. Despite the fact that I produce ozone gas from the generator, I can’t measure proper values at all. The sensor reads ppm when there is no ozone produced and goes down dramatically when it is produced. I am using the arduino code in this repository.

GitHub - ncd-io/MQ131: Ozone sensor with on-board ADC

MQ131. The MQ131 provides a high sensitivity Ozone measurement over a wide range. The NCD Mini Module pairs it with an on-board ADC making it easy to implement. This sensor requires what is known as a "burn in" time for the heating element in order to stabilize readings, the general recommended time is between 12 and 48 hours, in our tests the ...

MQ 131 when detecting ozone - Sensors - Arduino Forum

· Hi, There is two ways of using the MQ131: - directly the sensor itself (bare / naked sensor) - via a module I used to have a module and I remove the sensor from the module because the documentation doesn’t exist. The two important things are: 1. You have to preheat the sensor for 48h at 5V to have consistent result. 2. In order to compute the ppm/ppb, you have to calculate the Rs/R0 and ...

MQ-131 Module Ozone Gas Detection Ozone Sensor Module

MQ131 Ozone Gas Sensor Module is a compact board based on the MQ-131 sensor. It is equipped with a very wide range sensitivity to ozone which able to detect ozone concentration up to (10~1000ppb) in ambient air. The tin dioxide (SnO2) is the sensor's sensitive material, has a low conductivity (high resistance) in a clean air environment, and react really good in a presence of ozone. Thus ...
