LDR MODULE

A Light Dependent Resistor (LDR) module senses ambient light levels and adjusts electrical resistance accordingly. It is widely used in automatic lighting systems, smart streetlights, and solar tracking applications. The module contains an LDR sensor and a signal processing circuit. It provides digital and analog outputs for easy interfacing with microcontrollers. The resistance decreases with increasing light intensity, allowing for adaptive lighting control. It helps in energy conservation by turning lights on/off based on environmental brightness. The module is highly sensitive and has a fast response time. It is commonly used in security systems for automatic night lighting. LDR modules are durable, cost-effective, and efficient for smart home automation. They play a crucial role in IoT-based lighting solutions.
