The Haitronic KY-032 infrared sensor detects obstacles at a distance of 2–40 cm and outputs 0 when an object is detected. The detection distance is affected by the color and reflectivity of the surface, while the operating angle is 35°. It can be used for obstacle avoidance, line following, fall detection, product counting, cutting-line detection, and liquid-level detection.
It connects directly to a 3 V or 5 V microcontroller input/output port. Sensitivity and the infrared emission frequency can be adjusted using the corresponding resistors, while the EN input enables or disables the sensor.
