LM393 Photosensitive light dependent resistor LDR sensor module

The LDR light sensor module is used to detect the presence of light. It can measure the intensity of light. The output of the module goes high in the presence of light and it becomes low in the absence of light. The sensitivity of the signal detection can be adjusted using the potentiometer. We can use the LDR light sensor module for controlling the loads based on the intensity of light.
