Light Sensor Unit with Photo-resistance

Description

LIGHT Unit is a light intensity detection sensor that integrates a photoresistor and a 10K adjustable resistor. It is capable of detecting light intensity and setting a threshold value for light intensity. The resistance of the photoresistor decreases as the incident light intensity increases. By detecting the voltage change, the sensor obtains light intensity data through analog-to-digital conversion.

To achieve more accurate light intensity detection, this unit also incorporates an LM393 dual differential comparator. It is used to compare the differential voltage between the photoresistor and the pressure-sensitive resistor.
