MQ131 Ozone (O3) Gas Sensor Thingbits Electronics

The measuring circuit consists of the MQ131 sensor, a power source and a load resistor (RL) between the output pin and GND. The sensor with its internal resistance forms a voltage divider with the load resistor. The RL is designed as a variable resistor, allowing the output voltage to be trimmed to the desired value. The calibration should be performed in controlled conditions, as the ...

How To Use MQ135 Gas Sensor Codrey Electronics

20200705· yassin: RLOAD 10000 is for 1oK Load Resistor! As clearly pointed in this post, while using the “MQ135” librarysupported Arduino setup, the gas sensor calibration can be done at by finding the value of Ro in fresh air, and then using that value to find Rs through the formula: Rs = (Vcc/VRL1)x RL, that means Rs = (5V/(sensorValue * (/))1)*RL.
