LIGHT Sensor Unit

M5Stack LIGHT Sensor Unit is a light intensity sensor unit with an adjustable photoresistor. This photoresistor is a light-controlled variable resistor and the resistance of the photoresistor decreases with increasing incident light intensity and vice versa. This light sensor exhibits photoconductivity to detect the light that varies based on voltage and uses analog to digital converter to convert the digital data. The sensor unit includes LM393 dual differential comparators that compare the differential voltage between the photoresistor and the varistor. These comparators offer a larger and accurate range of light intensity.
