5mm LDR (Light Dependent Resistor)

Product Description:
Detect light levels in your electronics projects with this compact and reliable 5mm LDR (Light Dependent Resistor). Also known as a photoresistor, this sensor changes its resistance based on the intensity of light falling on it — making it ideal for building automatic light switches, street lights, light meters, and daylight-activated devices.

Perfectly compatible with Arduino, Raspberry Pi, and other microcontroller platforms, the 5mm LDR is a must-have for anyone working on light sensing, automation, and smart home projects.
