Air quality 5 Click Board
Air quality 5 click is a triple MOS sensor on a single Click board™, which can detect gas pollution for a number of different gases. The onboard sensor is specially designed to detect the pollution from automobile exhausts, as well as the gas pollution from the industrial or agricultural industry. This Click board™ uses the MiCS-6814, a compact MOS sensor with three fully independent sensing elements in one package: RED sensor, OX sensor, and NH3 sensor. Each of these sensors reacts with the specific type of gases, providing gas readings that including carbon monoxide (CO), nitrogen dioxide (NO2), ethanol (C2H5OH), hydrogen (H2), ammonia (NH3), methane (CH4), propane (C3H8), and isobutane (C4H10). Measurement conversion is handled by the onboard 12bit ADC converter and it is available via the I2C interface.
