TCS TT2000a Light Level Sensor

Outdoor Analog Light Sensor
Availability: In stock


The TT2000A light level sensor is designed to provide precise measurement of outdoor ambient light level. The light level measured is converted to an analog signal that is sent back to the controller. This allows the lighting controller to control inside lighting by switching banks of lights on and off or overriding outside lights in the event of overcast skies or darkening conditions. The TT2000A provides a continuous signal which can also be used by electronic dimming ballasts in fluorescent fixture.
