The DSM501B PM2.5 Dust Sensor Module can sense tobacco smoke, pollen, and house dust from heating automatic suction devices. An adjustable resistance is set up to detect the size of the dust. Using the same particle counter principle as the foundation, we can detect the absolute number of particles per unit volume.
