This Grove – Light Sensor is a “panel mount” version of original Grove – Light Sensor. They are identical except the Grove connecter is moved to the back so that you can easily use it as a neat and wire-free human interface device.

The Light sensor module uses the GL5528 photoresistor to detect the light intensity of the environment. The resistance of the sensor decreases when the light intensity of the environment increases. The chip LM358 is used as a voltage follower to enable you get a accurate data.
