20 Piece Dope IR Infrared Obstacle Avoidance Sensor Module Kit With 3 Wire Reflective Photoelectric Sensor For Arduino Raspberry Pi And Smart Car Robots DIY Projects
✔️ 20 IR obstacle sensors, 2-30 cm range, 3-5V, LM393 output
These infrared obstacle avoidance modules use a transmitting and receiving pair to detect objects via reflected IR light. When an obstacle reflects the beam, the green LED lights and the OUT pin pulls low, signaling your microcontroller to take action. They are great for Arduino, Raspberry Pi, smart cars, line following robots, and DIY robot kits.
✅ 2-30 cm detection distance with 35-degree view angle
✅ Digital OUT pulls low on detection, compatible with 3.3-5V MCUs
✅ 3-wire interface: VCC, GND, OUT; LM393 comparator on board
✅ Red power indicator shows when power is on
✅ Board size 3.1 x 1.5 cm with 3 mm mounting holes
✅ Includes 20 pieces for quick prototyping
✅ LM393 comparator with factory preset threshold
