Light Sensors


The LMHT-1ZW is a wireless Z-Wave ambient light, temperature and humidity 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 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. It provides the best way to monitor home environment and creating comfortable living environment.

The effective security solution provided by the LMHT-1ZW has residential and commercial applications. It can be installed in the homes of elderly individuals to make their independent living safer. It can also be used in gas stations, convenience stores, hospitals, or other establishments where employees have to work during late hours. When pressed in times of distress, the button triggers a silent alarm to bring emergency assistance to the user.

The LMHT-1ZW reports and transmits temperature and humidity condition, providing timely and actual indoor environment conditions.

As a Z-Wave device, the LMHT-1ZW can be flexibly integrated into new or existing Z-Wave systems.
