Light Sensors

LM-1ZW

LM-1ZW is a Z-Wave ambient light sensor that measures and reports variations in light intensity regularly. 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 can also be deployed in home automation and security networks to control the on/off status of devices and appliances based on ambient light levels. LM-1ZW 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.

LM-1ZW is water resistant to IPX4 standard. It is compatible with other manufacturers’ Z-Wave system and can be flexibly integrated into new or existing Z-Wave systems.
