mq131 module low concentration wiring

How to use MQ gas sensor using arduino -

· VCC and GND are used to power up the sensor module. Digital Out used to give output High/Low when the gas concentration reach the threshold. So it will only give digital signal. Analog Out will give analog voltage according to gas concentration. More concentration will give more voltage output. Since we will read the gas concentration, we use the analog output. Here is the wiring …

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 ...
