1. The 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 (reflecting surface), the infrared rays are reflected back by the receiving tube After receiving and processing by the comparator circuit, the green indicator light will light up, and the signal output interface will output a digital signal (a low-level signal). The detection distance can be adjusted by the potentiometer knob. The effective distance range is 2-30cm, and the working voltage is 3.3. V-5V. 2. The detection distance of the sensor can be adjusted by a potentiometer, which has the characteristics of low interference, easy assembly, and convenient use. 3. Widely used in many occasions such as robot obstacle avoidance, obstacle avoidance trolley, assembly line counting and black and white line tracking. 4. 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-IO 5. The comparator adopts LM393, which works stably; 6. The module can be powered by 3-5V DC power supply. When the power is turned on, the red power indicator lights up; 7. With 3mm screw hole, easy to fix and install; 8. Circuit board size: 3.2CM x 1.4CM 9. Module interface description -VCC external 3.3V-5V voltage (can be directly connected with 5v single-chip microcomputer and 3.3v single-chip microcomputer) -GND External GND -OUT small board digital output interface (0 and 1)
