Ziihao 10PCS IR Infrared Obstacle Avoidance Sensor Module 3-Wire Reflective Photoelectric for Arduino Smart Car Robot Raspberry Pi 3
Module descriptionThe sensor module has strong adaptability to ambient light. 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 (reflective surface), the infrared rays are reflected back and received by the receiving tube. After being processed by the comparator circuit, the green indicator light will light up. At the same time, the signal output interface outputs a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective distance range is 2～30cm. The working voltage is 3.3V- The detection distance of the 5V sensor can be adjusted by a potentiometer. It has the characteristics of low interference, easy assembly, and convenient use. It can be widely used in many occasions such as robot obstacle avoidance, obstacle avoidance trolley, assembly line counting and black and white line tracking.Module parameter description1.When the module detects the front obstacle signal, the green indicator on the circuit board lights up, and the OUT port continues to output low-level signals. The detection distance of the module is 2～30cm, the detection angle is 35°, and the detection distance can pass the potential. Adjust the potentiometer clockwise to increase the detection distance; adjust the potentiometer counterclockwise to decrease the detection distance.2.The sensor takes active infrared reflection detection, so the reflectivity and shape of the target are the key to the detection distance. Among them, the black detection distance is small, and the white is large; the distance of a small area object is small, and the distance of a large area is large.3.The output port OUT of the sensor module can be directly connected to the IO port of the single-chip microcomputer, or it can directly drive a 5V relay; connection mode: VCC-VCC; GND-GND; OUT-IO4.Th
