LIGHT is a light intensity sensor unit with an adjustable photoresistor.
A photoresistor is a light-controlled variable resistor. The resistance of a photoresistor decreases with increasing incident light intensity, and vice versa. It exhibits photoconductivity which makes it possible to detect the varies based on Voltage, and use an AD to convert the digital data.
We add some extra work to strengthen the circuit, a Dual Differential Comparators LM393, compares the differential voltage between the photoresistor and the varistor. It could offer a larger and accurate range of light intensity.
