GL5528 Light Sensor
This light sensor is based on the GL5528 photo resistor to detect the light intensity of the environment. The resistance of the sensor varies depending on the amount of light exposed, the output voltage changes depending on the light intensity. This module outputs in both analog and digital signals. The potentiometer can be used to adjust the sensitivity of both the analog and digital output. The terminal output HIGH when the light intensity exceeds the value set by potentiometer.
