Pollution Click Board
The Pollution Click Board has high sensitivity to organic gases such as methanal (also known as formaldehyde), benzene, alcohol, toluene, etc. The click carries the WSP2110 VOC gas sensor with the detection range of 1-50ppm (parts per million).
The Pollution click is designed to run on a 5V power supply. It communicates with the target MCU via the AN and RST pins on the MikroBUSline.

WSP2110 VOC gas sensor
WSP2110 VOC gas sensor is a MOS type (metal oxide semiconductor) sensor that detects volatile organic compounds such as methanal, benzene, alcohol and other types of gases that can be harmful to one's health in high concentrations. .
The concentration of the target gas affects the conductivity of the sensor. Higher concentration of the gas means the conductivity of the sensor gets higher as well.
For precise calibration, the sensor needs to preheat (once powered up, it takes 120h to reach the right temperature).
P1 potentiometer onboard is used for trimming the sensor's sensitivity. Enable the pin drive gate of heaters MOSFET switch to reduce power consumption when the click is not in use.
The detection range of the sensor is 1-50ppm (part per million). Parts per million is the numbers of parts of a component in 1 million parts of the gas mixture, it's the ratio of one gas to another.
Volatile organic compounds
Volatile organic compounds or VOCs are organic chemicals. They have very high vapor pressure at room temperature, and some of them can be harmful to human health. As most people spend a lot of time indoors it's important to know if the quality of the air is good. With the Pollution click, you could always know if your indoor environment is healthy.
