Mikroelektronika MIKROE-2767 Ozone 2 Click Board MQ131 Gas Sensor

Technical description of the product (MIKROE-2767):

The Mikroelektronika MIKROE-2767 Ozone 2 Click Board is an Ozone detection (O3) sensor, based on the MQ131 gas sensor. This gas sensor has a sensitive layer made of SnO2, which changes its resistance when exposed to ozone. The sensor is able to sense O3 concentration in the range of 10 ppm to 1000 ppm. The Click Board is also equipped with a trimmer potentiometer, used to adjust the sensitivity and offset of the MQ131 sensor. Low cross-influence of other oxidation gases such as CL2 and NO2 ensures good accuracy of the sensor. The analog output of the sensor is sampled by a high-resolution 22-bit A/D converter (ADC), which offers the conversion result on the SPI interface. The analog signal from the sensor is also available, allowing an external ADC to be used. Ideal for air quality control or gas leak detection.
