LDR MODULE 3-PIN

LDR Sensor Module – 3-Pin

The 3-Pin LDR Module detects light intensity using a photoresistor (LDR). It provides a simple way to trigger actions based on ambient light — perfect for light-sensitive automation and Arduino projects.

Key Features:

• Detects ambient light levels

• 3-pin interface: VCC, GND, DO (Digital Output)

• Adjustable sensitivity via onboard potentiometer

• Operating Voltage: 3.3V – 5V

• Easy integration with Arduino, ESP32, Raspberry Pi, and more

Applications:

• Automatic lighting systems

• Light-activated alarms

• Solar trackers

• Smart home automation

• DIY electronics projects
