KY-033 (Infrared Line Tracking Sensor for Arduino)

Description:

Infrared obstacle avoidance sensor is designed for a wheeled robot. The obstacle avoidance sensor is distance adjustable. This ambient light sensor is adaptable, high precision, and has a pair of infrared transmitters and receivers. The transmitter tubes emits a certain frequency of infrared when detecting the direction of an obstacle (reflector), and the infrared receiver tube receiver is reflected back when the indicator is lit. Through the circuit, the signal output interface can be detected by means of the potentiometer knob to adjust the distance, and the effective distance from 2 ~ 40cm, working voltage 3.3V-5V, operating voltage range as broad, relatively large fluctuations in the power supply voltage of the situation stable condition and still work for a variety of microcontrollers, Arduino controller, BS2 controller when attached to the robot that can sense changes in their surroundings.
