Mq 135 Gas Sensor

Output voltage boosts along with the concentration of the measured gases increases. Since ao is a varying voltage this pin should be connected to one analog input of a microcontroller the do pin is an open collector digital output but with a pull up resistor onboard that becomes low when the detection level exceeds a predefined level. When the level of these gases go beyond a threshold limit in the air the digital pin goes high.
