Grove - Dust Sensor Introduction . This Dust Sensor gives a good indication of the air quality in an environment by measuring the dust concentration. The Particulate Matter level (PM level) in the air is measured by counting the Low Pulse Occupancy time (LPO time) in given time unit. LPO time is proportional to PM concentration.
The sensor provides a continuous monitoring signal to indicate dust accumulation in the valve body that may prevent the valve flaps from fully closing should a deflagration occur. The DLA is a capacitive sensor with field adjustable gain that can be calibrated to trigger at or above 10 mm ( in) dust accumulation based on the bulk properties of
