Indoor air quality monitoring

SmartClean’s air quality measurement sensor is a battery operated sensor that measures the following environmental parameters:

• Indoor Air Quality (IAQ), Temperature, Humidity: The IAQ index, temperature and relative humidity is derived from the measurements by Bosch BME680 module. A detailed note on its functionality and measurement parameters can be found here and here.

• Ammonia (ppb): This metric is measured using an electrochemical sensing module from Semiatech. Values are measured in units of parts per billion. The datasheet can be found here.
