MQ2 Smoke/LPG/CO Gas Sensor Module | Sandbox Electronics

The sensor’s resistance R S and R L forms a voltage divider. The output voltage on the signal pin could be read by Arduino or MCU via ADC. Given a value of R L , Power Supply Voltage, and output voltage, R S could be derived. Based on the chart provided in the MQ2 datasheet, R S in clean air under given temperature and humidity is a constant,which is the “initial” resistance of the ...
