SKU: fb7cc3315c8c Categories: , Tags: ,


Our Wireless Battery-Free Light Sensors save time, energy, and money by avoiding costly and time-consuming installation of hardwired daylighting controls.

The light sensor saves energy by lowering the output of artificial light when daylight is present in a room, saving up to 60% of the electrical energy used on lighting.

The wireless sensor works in conjunction with wireless relays, dimmers, room and task on/off controllers and can integrate into other automation systems.

The sensor can be used in open-loop and closed-loop daylight-harvesting applications, is RoHS compliant, qualifies for LEED credits and helps buildings comply with International Green Construction Code Standard 189.1. When fully charged the sensor can work in total darkness for up to four days.
