10pcs Infrared Obstacle Avoidance Sensor Module for Arduino Smart Car Robot, 3-Wire Reflective Photoelectric Sensor for Arduino Smart Car Robot

General Description

This infrared obstacle avoidance sensor module is designed for smart car robots using Arduino.

It can detect obstacles at a distance of 2 to 30 cm with a detection angle of 35°.

When an obstacle is detected, a green LED lights up and the OUT port emits a weak signal. The module uses active infrared reflection to determine the distance, which can be adjusted using a potentiometer. Technical Specifications: Detection Distance: 2-30 cm; Detection Angle: 35°; Supply Voltage: 3-5V DC; Board Size: 3.2 cm x 1.4 cm; Output Port: Digital (0 and 1); Compatibility and Accessories: Compatible with Arduino microcontrollers; Can directly drive a 5V relay; Each package includes 10 infrared sensor modules. Installation: Easy mounting via 3 mm screw holes. Usage: Connect VCC to VCC, GND to GND, and OUT to IO 4 on the microcontroller. Adjust the detection distance using the potentiometer.
