KY-032

Infrared obstacle avoidance sensor is a distance adjustable obstacle avoidance sensor designed for wheeled robots. This sensor has strong adaptability to ambient light and high precision. It has a pair of infrared emitting and receiving tubes. The emitting tube emits a certain frequency of infrared rays. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back by the receiving tube When receiving, the indicator light is on. After the circuit is processed, the signal output interface outputs a digital signal. The detection distance can be adjusted by the potentiometer knob. The effective distance is 2~40cm, and the working voltage is 3.3V-5V. Due to the wide working voltage range, It can still work stably even when the power supply voltage fluctuates greatly. It is suitable for a variety of single-chip microcomputers, Arduino controllers, and BS2 controllers. It can be installed on the robot to sense changes in the surrounding environment.
