LDR MODULE
An LDR Module is a light-sensing electronic module that detects the intensity of light in its surroundings. It works on the principle of a Light Dependent Resistor (LDR), whose resistance changes according to the amount of light falling on it. When light intensity increases, resistance decreases, and when light intensity decreases, resistance increases. This module is widely used in automatic lighting systems, security systems, and smart electronics projects.
