KY-032 Infrared Obstacle Avoidance Sensor Module

Description

About this item:

The KY-032 is a reliable infrared sensor module designed for robotics and automation projects to detect nearby objects and prevent collisions. It works by transmitting and receiving IR signals to determine if an obstacle is present.

Key Features:

• Working Voltage: 3.3V – 5V DC

• Detection Distance: Adjustable (≈ 2 cm to 30 cm)

• Detection Angle: ≤ 35°

• Signal Output: Digital (LOW when obstacle detected, HIGH when clear)

Onboard Components:

• Infrared transmitter and receiver

• LM393 Comparator IC

• Potentiometer for distance sensitivity adjustment

• Output indicator LED

Applications: Robotics, automation, obstacle avoidance systems, smart cars, and DIY electronics
