23/09/2020· Hi there! 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 ...

12/01/2018· The MQ131 ozone gas sensor is capable of sensing ozone air concentration levels between 10ppb and 2ppm. The ideal sensing condition for the MQ131 is 20°C ±2°C at 65% ±5% humidity. This Device is available from [SKU: ADC121C_MQ131_I2CS]
06/06/2021· I’m working with the Ozone sensor model Mq-131 and one module KS123-35Y500K in an Arduino UNO. A link to that board would help. This library makes the conversion to ppb. Remember the conversion of the read analog value is also based on the humidity of the air around the sensor as well as the type of sensor (there are two versions named MQ131 ...
Library for measuring ozone (O3) concentration with sensor MQ131 This library supports low concentration (WO3 and SnO2 versions) and high concentration sensors and accept variable load resistance.
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.
The MQ131 ozone gas sensor is capable of sensing ozone air concentration levels between 10ppm and 1000ppm. The ideal sensing condition for the MQ131 is 20°C ±2°C at 65% ±5% humidity. An internal preheater inside the sensor helps achieve the ideal sensing conditions, but the datasheet recommends over 24 hours for preheating to achieve optimal accuracy. Because of the internal preheater, this …
Sensitive material of MQ131 gas sensor is O3 SnO2, which with lower conductivity in clean air. When Ozone gas exists. The sensor’s conductivity is more higher along with the gas concentration rising. Please use simple electro circuit, Convert change of conductivity to correspond output signal of gas concentration. MQ131 gas sensor has high sensitivity to Ozone, also sensitive to O3 CL2, NO2, etc.

04/11/2020· I'm using the mq131 Ozone sensor on an ESP32 (rather than Arduino) which internal operating voltage (and max ADC input) is Hence I'm feeding the sensor with instead of 5V. Would it work if I change the library and just change (for 5V Arduino) to (for ESP32)? I mean at the readRS() function float MQ131Class::readRs()
06/05/2021· i connect mq131 to arduino i preheated the mq131 two i start the program i measured approx 700in ambient 2 days i measured approx 300 in ambient i expose the ozone to the mq131 sensor it is decreasing suddenly to 1 or 0...Why?? is it working reverse? i couldnt understand it?Can you help me i am beginner.
