LIGHT is a light intensity sensor unit with an adjustable photo-resistor。

A photo-resistor is a light-controlled variable resistor. The resistance of a photo-resistor decreases with increasing incident light intensity and vice versa. The sensor exhibits photoconductivity which make it possible to detect the light varies based on voltage and use an AD (Analog to digital converter) to convert the digital data.

We added some extra work to strengthen the circuit, a Dual Differential Comparators LM393, compares the differential voltage between the photo-resistor and the varistor. It could offer larger and accuracy range of light intensity.
