Infrared Obstacle Avoidance Tracking Sensor Module

The sensor module has strong ability to adapt to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared light of a certain frequency. Signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the working voltage is 3.3V.5V. The sensor's detection distance can be adjusted by a potentiometer, has small interference, is easy to assemble, and is easy to use. It can be widely used in robots to avoid obstacles, avoid cars, count pipelines, and track black and white lines. Sensor module output port OUT can be directly connected with the microcontroller IO port can also directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO. When the module detects an obstacle in front of the signal , the green indicator light on the board level , while low-level continuous output signal OUT port , the module detects the distance 2 ~ 30cm, detection angle 35 °, the distance can detect potential is adjusted clockwise adjustment potentiometer to detect the distance increases ; counterclockwise to adjust the potentiometer to reduce the detection distance . Active infrared sensors to detect the reflected , and thus the shape of the reflectivity of the target detection range is critical . The minimum detection distance which black , white maximum ; small objects from a small area , a large area from the Grand . The output port OUT sensor module can be directly connected to the microcontroller IO port , you can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO Using the comparator LM393, stable ; Can be used for 3-5V DC power supply modules . When the power is turned on, the red power.
