The Photosensitive Sensor Module w/ 3-Pin Cable can be used to measure light levels. It utilizes a photo transistor to generate an output voltage which will vary depending on the light levels. Connect it to an Arduino or any other development board to construct a night/day sensor, a sun tracker, or combine it with a laser module to create a laser trip wire.
