LDR Light Sensor Module

The LDR (Light Dependent Resistor) Light Sensor Module is a compact and efficient tool for detecting ambient light intensity, ideal for use in automatic lighting, solar tracking systems, IoT devices, and Arduino projects. It works by measuring light levels using an LDR, which changes resistance based on the amount of light it receives.

Equipped with both analog and digital outputs, this sensor can be easily integrated into a variety of microcontroller platforms, including Arduino, ESP32, and Raspberry Pi. With an onboard sensitivity adjustment potentiometer, you can fine-tune the light threshold for digital triggering.

Key Features:

• Detects light intensity using LDR (Photoresistor)
• Operating Voltage: 3.3V – 5V DC
• Dual output: Analog and Digital
• Adjustable sensitivity using onboard potentiometer
• Compatible with Arduino, ESP8266, Raspberry Pi, and more
• Ideal for automatic light control, solar tracking, and IoT applications

Applications:

• Smart lighting systems
• Light-sensitive alarms and triggers
• Solar panel positioning systems
• IoT-based environmental monitoring
• Educational electronics kits
