2021-05-06· I just start to use MQ131 module. First, I already preheat MQ131 in 48 h but I used 5V from USB after that I try to calibrate sensor but it not stable. I want to know, what should I do to use this sensor. Thank you very much. Tai
2019-02-19· More than 400 PPM of ozone from my product. Hardware Configuration Arduino Uno + Arduino Uno Compatible I2C Shield + Ozone Gas Sensor 12-Bit (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. What is it? Ask for help. Attachment (code, photo) #include …
2021-05-06· 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.
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]
2021-05-06· How do I convert bits value shown in serial monitor to ppm? I need help with code.
2020-09-30· MQ131 Ozone sensor measurement. unluz September 30, 2020, 11:57am #1. 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 ...
