Air Quality Click Board, mikroE
Air Quality Click Board, mikroE

Air quality click board features MQ-135 gas sensor in its design for measuring the air quality in apartments, homes and offices. This add-on board helps the users in detecting poisonous gases like ammonia (NH3), nitrogen oxides (NOx), benzene, CO2, smoke and others that harm the air quality, and pollute it. Air quality click is equipped with a calibration potentiometer and a power indicator LED. It also has got a mikroBUS host socket and two jumpers. The MQ-135 sensor features a gas sensing layer constructed of tin dioxide which is an inorganic compound with the formula SnO2. Tin dioxide is known to have lower conductivity in clean air.

As the level of pollution increases in the air, the conductivity rises too. User can calibrate Air quality click for the environment by adjusting the load resistance of the sensor circuit. As the concentration of the target air changes, the resistance of the sensor component also gets changed.

Gas sensor: MQ-135

MQ-135 gas sensor is highly sensitive to air polluting gases like Ammonia, Sulfide and Benze steam and has a fast response time. The sensor features a simple drive circuit and has got a long life. It is also sensitive to smoke and other harmful gases.

Voltage Requirements

Air quality click has been designed to consume a 5V power supply only. This accessory board uses AN (OUT) mikroBUS line for communicating with the target board.


Air quality click finds useful application in designing of air quality detection equipment. This click board can be used in the devices like domestic air pollution detectors, industrial air pollution detectors and portable air pollution detectors since it is highly suitable for detecting the concentration of poisonous gases in the air.
