Sensor Modules

Telaire Laser Dust Sensor SM-UART-01L+

new Telaire SM-UART-01L+ Laser Dust Sensor detects dust particle concentration in air by using an optical sensing method. 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.

Telaire VOC Sensor Module

MiCS-VZ-89TE combines state-of-the-art MOS sensor technology with intelligent detection algorithms to monitor tVOCs and CO2 equivalent variations in confined spaces.

SMART Dust Sensor

SM-PWM-01C is a dust sensor that detects the dust particle concentration in air by using optical sensing method.
