IR Obstacle Avoidance Sensor Module

Infrared Obstacle Avoidance Proximity Sensor Module

Designed for autonomous collision avoidance in wheeled robotic platforms, this module projects an infrared beam and detects reflection from nearby obstacles. An onboard trimmer allows precise calibration of stopping distance from 2 cm to 30 cm.

• Detection Range: 2 cm to 30 cm (adjustable via potentiometer)
• Detection Angle: 35 degrees cone
• Operating Voltage: 3.3V to 5.0V DC
• Output Signal: Active-low digital signal (0 when obstacle detected)
• Comparator: LM393 with status and power LEDs
• Dimensions: 32 mm × 14 mm with 3 mm mounting hole
