LIGHT DETECTION SENSOR MODULE 4 PIN

💡 Light Detection Sensor Module (4-Pin) – Smart Brightness Sensing for Automation & Robotics
The 4-Pin Light Detection Sensor Module uses an LDR (Light Dependent Resistor) to detect surrounding light intensity. It's ideal for automatic lighting control, day/night detection, light-following robots, and energy-efficient smart systems. 🌞🌒

🔧 Key Features
📟 Sensor Type: LDR-based light sensor
🔌 Interface Pins: VCC, GND, A0 (Analog), D0 (Digital)
💡 Output Modes: A0 (Analog signal – real-time light intensity), D0 (Digital signal – HIGH/LOW output based on threshold)
🔧 Adjustable sensitivity via onboard potentiometer
⚡ Operating Voltage: 3.3V–5V DC
📶 Power & Signal LED indicators

📦 Package Includes
✅ 1x Light Detection Sensor Module (4-Pin)
📄 Pinout: VCC, GND, A0, D0
🧰 Compatible with Arduino, ESP32, Raspberry Pi, STM32, ESP8266, etc.

🧠 Perfect For
💡 Auto ON/OFF lighting systems, 🌗 Day & night detection, 🤖 Light-following/avoiding robots, 📦 Energy-saving automation, 🎓 STEM & DIY electronics

🛠️ How It Works
LDR detects ambient brightness → A0 gives analog output → D0 gives digital HIGH/LOW based on threshold → Triggers lights, buzzers, relays, or logs data.

💡 Pro Tip: Pair with a relay module to automate lights/fans based on sunlight!
