LDR 5mm

LDR 5mm Light Dependent Resistor

The LDR 5mm (Light Dependent Resistor) is a simple and cost-effective light sensor that changes its resistance based on light intensity. As light increases, the resistance decreases, making it ideal for detecting brightness levels in electronic circuits.

Commonly used with Arduino, ESP32, ESP8266, and other microcontrollers, this 5mm LDR is perfect for automatic lighting systems, light-sensitive alarms, and DIY electronics projects.
