How To Use MQ-135 Gas Sensor - Codrey Electronics

· Thereafter, introduce the MQ-135 sensor to the gas you want to detect and slowly adjust the trimpot until DO gets low. I tested my module with isopropyl alcohol, cigar lighter gas, perfumed body spray, and the breath of mine. Now every time your sensor gets introduced to that gas at predefined concentration, DO will go low (0V) else will remain high (5V). Note that the green LED (OUT_LED ...
