How To Use MQ135 Gas Sensor Codrey Electronics

20200705· 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) should also light up when gas is observed. Also note that when the sensor is powered up for gas detection, it needs around 60120 seconds to settle, because the heater will need that much time to heat the sensor up. Remember, the ...
