Light Sensor

Our Light Sensor is perfect for sensing the brightness of an environment. It outputs a fully conditioned signal in the industry standard voltage range of 0.25-4.75 Volts, perfect for the Teabox.

As with all of our sensors, we have taken care to make certain that this sensor is of high quality. For the hacker or do-it-yourselfer we also offer a "project version" of this sensor (see the specification sheet for more details), which comes at a reduced price.
