Arduino Light Sensor Switch Module
Module is used to detect ambient light. The sensor is a CDS photo resistor connected to a LM393 voltage comparator IC with adjustable sensitivity control (R6). The LED indicator that turns on when dark or low light is detected. The output can be connected directly to a micro-controller I/O port or a relay. Ideal for turning on lights automatically at night.
