It runs off our Batteryboard and has two modes: simply connect the sensor in your circuit to sense "light" or dark". Easy to use with textile, paper, and other materials.In "light sense" mode the sensor will trigger an output to turn on when it senses light, and turn off when it sense dark
In the "dark sense" mode sensor will trigger an output to turn on when it senses dark and turn off when it senses light.
