## Description

This Elecrow 4-channel IR reflective sensor module combines four infrared emitter/receiver pairs with a mainboard that processes all signals. When an object enters the detection range, the corresponding channel outputs a low (TTL 0) signal and its indicator LED lights up. Each channel has an onboard potentiometer for adjustable detection range from 1mm to 60cm. The module runs on 3.3V to 5.5V, making it compatible with both 3.3V and 5V microcontrollers. It is well-suited for robotics applications such as line following, edge detection, and obstacle avoidance. Key Features 4 Independent IR Channels – Each channel has its own IR emitter, receiver, indicator LED, and sensitivity potentiometer Adjustable Detection Range – 1mm to 60cm, tuneable via onboard potentiometers TTL Digital Output – Low (0) when object detected, high (1) when clear Wide Voltage Range – 3.3V to 5.5V supply LED Indicators – Visual feedback for each channel's detection status Specifications Supply Voltage – 3.3V to 5.5V Supply Current – >1A recommended Detection Range – 1mm to 60cm (adjustable) Output – TTL digital (active low) Channels – 4 Ideal For Line-following robots Edge detection Obstacle avoidance Omni-directional object sensing Package Contents 1× 4-Channel IR Reflective Sensor Module
