Mikroelektronika MIKROE-1630 MQ-135 Air Quality Sensor Click Board, Potentiometer Calibration, 3.3V/

Technical description of the product (MIKROE-1630):

The Mikroelektronika MIKROE-1630 MQ-135 Air Quality Sensor Click Board carries an MQ-135 sensor for air quality detection. The gas sensing layer is made of tin dioxide (SnO2), which has lower conductivity in clean air. A potentiometer allows for calibration of the sensor. The board offers an analog interface and is compatible with 3.3V or 5V input voltage. It is ideal for air quality detection in homes and offices.
