PRODUCT NAME

Photosensitive Resistor Sensor Module for Arduino

PRODUCT DESCRIPTION

The Photosensitive Resistor Sensor Module (also called a light sensor or LDR module) is an electronic module that detects light intensity using a photosensitive resistor (LDR). As the amount of light changes, the resistance of the LDR changes, and the module converts this into an analog signal that can be read by microcontrollers like Arduino. It’s commonly used for light-level detection, automatic lighting, brightness control, and environmental sensing in various DIY and embedded projects.

KEY FEATURES
