Telaire SM-UART-01L Dust Sensor

Telaire SM UART 01L Dust Sensor

The Telaire SM-UART-01L Laser Dust Sensor detects dust particle concentration in air by using an optical sensing method consisting of a laser light emitting diode (LED) and a photo sensor that are optically-arranged in the device. The photo sensor detects the reflected laser LED light by dust particles in air. The dust sensor can detect small particles, such as cigarette smoke, and distinguish small particles, such as smoke from large house dust, by the pulse pattern of the signal output.
