LMHT

LMHT Sensor

Enables security systems to dim or switch on/off electric lighting in response to changing daylight.

LMHT is a wireless sensor that measures and reports variations in light intensity, temperature, and humidity. The device enables home automation and security systems to dim or switch on/off electric lighting in response to changing daylight availability so as to adjust brightness to an optimum level and reduce energy consumption. It provides the best way to monitor home environment and create a comfortable living environment.

LMHT features a spectral response mimicking the human eye’s perception of ambient light and incorporates IR and UV blocking capabilities. The sensor is an essential component of daylight harvesting solutions as it can effectively balance natural and artificial lighting in buildings according to daytime or evening conditions.

Compatible with ZigBee products supporting the ZigBee Pro HA 1.2 profile, it can be flexibly integrated into new or existing ZigBee systems.
