LDR Module

Detects light intensity levels

EDT - Electronic Device Transducer
The LDR (Light Dependent Resistor) is a light-sensitive component whose resistance varies with light intensity. Its resistance decreases in bright light and increases in darkness. It is widely used in automatic lighting systems, light meters, solar trackers, security devices, and electronics projects for light detection and control.
Operating Voltage 3.3V – 5V
Sensor Type Light Dependent Resistor
Output Type Analog Resistance Output
Resistance Range 200Ω – 1MΩ
