Arduino: Reading PPM values from MQ-131 Ozone sensor ...

I have this sensor MQ131 by sainsmart: https: ... For example if you have 100ppm CL2 and 200ppm O3, you'll read 300ppm on your arduino. If you want a sensor which will give you the ppm of only one gas, it will cost you much much more. – Vincent Teyssier Aug 14 '16 at 15:55.

MQ 131 when detecting ozone - Sensors - Arduino Forum

06/05/2021· 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 Sensor | MySensors Forum

07/05/2016· I didn't have to use any capacitors to improve range, they are directly connected to some medium-quality Arduino Nano GND/ One of them is a lighting controller node, ~3 meters from the PA/LNA gateway (+ a 30cm wall) on the same level as the gateway. The other one is a repeter node and is ~10 meters from the gateway (+ a 20cm wall, same level as the gateway). In this case, radio ...

MQ135 Sensor - calibrate and configure - DIY Projects

06/05/2020· MQ135 Sensors are usable as an air quality sensor for detecting a wide range of gases, including NH3, NOx, alcohol, benzene, smoke and CO2. For me, these sensors should be affordable by the price but also deliver acceptable measurements. That’s the reason I decided to test this MQ135 Sensor. Five of them are available in our region even with amazon for 11€ which make these little …
