PRODUCT DETAILS
Description
 
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. 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 photoresistor and the varistor. It could offer larger and accuracy range of light intensity.
