2Pcs KY-032 4pin IR Infrared Obstacle Avoidance Sensor Module Diy Smart Car Robot for Arduino TLL Photoelectric Switch Module
Features:
1. The infrared obstacle avoidance sensor is a distance adjustable obstacle avoidance sensor specially designed for wheeled robots.
2. 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 infrared rays of a certain frequency.
3. When the detection direction encounters an obstacle (reflecting surface), the infrared rays are reflected back and received by the receiving tube, and the indicator light is on at this time
4. After the circuit processing, the signal output interface outputs digital signals, and the detection distance can be adjusted by the potentiometer knob, the effective distance is 2?40cm
5. The working voltage is 3.3V-5V. Due to the wide working voltage range, it can still work stably in the case of large fluctuations in the power supply voltage. It is suitable for a variety of microcontrollers, Arduino controllers, and BS2 controllers. It can be installed on the robot. Sensing changes in the surrounding environment
