4 IR Array Module 4 Channel

The 4-Channel IR Sensor Array Module is a compact and efficient infrared sensor module that combines four IR transmitter-receiver pairs arranged in a linear array. It is designed for multi-point infrared sensing, making it ideal for applications like line-following robots, edge detection, and surface pattern recognition. Each channel operates independently and detects changes in reflectivity, allowing the module to differentiate between dark and light surfaces (e.g., black line on white background).

Specifications (Typical):

• Sensor Type: 4-Channel Infrared Reflective Sensor Array

• Number of Channels: 4 independent IR pairs

• Detection Method: Infrared reflectivity (light/dark surface)

• Output Type: Digital (typically HIGH/LOW for each sensor)

• Operating Voltage: 3.3V – 5V DC

• Output Format: 4 separate digital output pins (1 per sensor)

• Detection Distance: 2 mm to 12 mm (depends on surface)

• Response Time: <1 ms
