LDR Light Detection Resistance Sensor Module-3 Pin Photo

30.00 EGP

The LDR (Light Dependent Resistor) Sensor Module is a light-sensitive detection module that measures ambient light intensity using a photoresistor. With a 3-pin interface (VCC, GND, OUT), this module provides both digital (HIGH/LOW) and analog (variable voltage) outputs, making it ideal for light-triggered automation, security systems, and smart lighting projects.

Designed for Arduino, Raspberry Pi, and other microcontrollers, this module is widely used in energy-saving devices, weather stations, and DIY electronics.

Key Features

✔ Light-Sensitive Detection – Measures visible light intensity (low-light to bright environments).
✔ Dual Output Modes – Digital (TTL) + Analog for flexible integration.
✔ Adjustable Sensitivity – Onboard potentiometer to set light-detection threshold.
✔ LED Indicator – Lights up when light level crosses the set threshold (digital mode).
✔ Low Power Consumption – Operates at 3.3V–5V DC.
✔ Compact & Breadboard-Friendly – Easy to install in tight spaces.

Technical Specifications
