The KY-032 IR Infrared Distance Obstacle Avoidance Detection Sensor Module returns a signal when it detects an object within a fixed range which can be adjusted by the onboard potentiometer from 5 – 50 cm.
This module is an infrared detection system for smart cars, robots, and other automated mechanisms to provide a multi-purpose solution. The discreet infrared transmitter and receiver use the LM339 voltage comparator as a core device in the control circuit.
Ideal for obstacle avoidance robots, this module includes an Infrared transmitter and receiver placed side by side. If the IR from emitter gets reflected by any obstacle ahead, the receiver sensor detects it! The 2 potentiometer lets you adjust the intensity of the emitter and also the sensitivity of the sensor.
