How To Use MQ-135 Gas Sensor - Codrey Electronics

Jan 16, 2020 · The MQ-135 gas sensor has an inbuilt variable resistor (sense resistor) that changes its resistance value according to the concentration of gas. If the gas concentration is high, the resistance decreases, and if the gas concentration is low, the resistance increases. The MQ-135 gas sensor basically needs only one key component as the external component – just a load resistor.
