Infrared Obstacle Avoidance Sensor (KY-032)

Ky-032 is an infrared obstacle avoisance sensor. I can sense obstacles in front of moving robot at distance up to 40cm. The object (obstacle) detection distance can be adjusted using potentiometer. Infrared is emitted at a certain frequency, and when meet an obstacles (reflecting surface), reflected infrared is received and a digital signal ( low level signal) is detected at the OUT pin. Features • Effective Range: 2:40 cm (Adjustable by potentiometer) • Voltage Supply: 3.3: 5Vcc • Detection Angle: 35° • Size: 28mm × 23mm • Digital output: LOW obstacle detected / HIGH no obstacle Ky-032 infrared obstacle avoisance sensor operation guidance and arduino code
