How To Use MQ135 Gas Sensor Codrey Electronics

20200116· The MQ135 gas sensor module has four pins (standard male headers) as shown above. The air quality information is readable via the AO pin. Since AO is a varying voltage, this pin should be connected to one analog input of a DO pin is an opencollector digital output (but with a pullup resistor onboard) that becomes low when the detection level exceeds a predefined level.
