Deskripsi Sensor IR Infrared Obstacle Avoidance The sensor module light is adaptable to the environment, it has a pair of infrared transmitting and receiving tube, tube infrared emitting a certain frequency, when detecting direction meet with obstacles (reflecting surface), reflected infrared receiving tube, after the comparator circuit processing, green indicator will light up, at the same time signal output interface and output digital signal (a low level 0V) signal, can be adjusted through the potentiometer knob detection distance, effective distance range 2 ~ 30 cm, the working voltage of 3.3 V to 5 V.The detection range of the sensor can through the potentiometer to adjust and have small interference, easy to assemble, easy to use, etc, can be widely used in robot obstacle avoidance, obstacle avoidance car, line count and black and white line tracking and so on many occasions.
Wire 1. VCC external 3.3V to 5V voltage (which can be directly connected to 5V microcontroller or 3.3 V microcontroller) 2. The GND external GND 3. The OUT small plate digital output interface (0 and 1)
