Technical Specifications 📐

• Operating Voltage: 3.3V to 5V
• Detection Range: 2 cm to 30 cm (actual range depends on target size and surface reflectivity)
• Interface: Digital output (logic-level compatible with 3.3V–5V systems)
• Dimensions: 3.2 cm × 1.4 cm

Compatibility and Integration 🔌

Works seamlessly with popular development boards and ecosystems:

• Arduino: Connect VCC (3.3–5V), GND, and OUT to a digital GPIO pin. Read HIGH/LOW for obstacle presence.
• Raspberry Pi: Power from 3.3V and read the digital OUT via a GPIO input. No level shifting required at 3.3V operation.
• Compatible with other microcontroller modules (ESP32, ESP8266, STM32) that accept a digital input.

Typical Applications 🚀

• Robotics 🤖: Obstacle avoidance, edge detection, and wall-following.
• Security systems 🔒: Trigger alerts on unexpected movement or proximity.
• Interactive art installations 🎨: Proximity-triggered light, sound, or motion effects.
• Home automation 🏠: Smart control of appliances or lighting based on obstacle presence.

Usage Tips and Best Practices 🧠

• For maximum range, target larger, light-colored, and reflective surfaces; dark or absorbent materials may reduce detection distance.
• Avoid direct sunlight or strong IR sources to minimize interference.
• Adjust the onboard sensitivity control to set your preferred trigger distance within the 2–30 cm range.
• Use a pull-up/pull-down on the microcontroller input if needed for clean, noise-free readings.
