Air Quality Click is a simple solution for adding a high sensitivity sensor for detecting a variety of gases that impact air quality in homes and offices. It carries an MQ-135 sensor and is designed to run on a 5V power supply. The click communicates with the target microcontroller over the AN pin on the mikroBUS line.
It is suitable for detecting gases like ammonia (NH3), nitrogen oxides (NOx), benzene, smoke, CO2, and other harmful or poisonous gases that impact air quality. The MQ-135 sensor unit has a sensor layer made of tin dioxide (SnO2), an inorganic compound that has lower conductivity in clean air than when polluting gases are present.
To calibrate Air Quality Click for optimum performance, use the onboard potentiometer to adjust the load resistance on the sensor circuit.
Applications: Air quality detection for homes and offices.
