10Pcs IR Sensor Infrared Sensing Sweep Proximity Sensor Module

IR Infrared Obstacle Avoidance Sensor ModuleThis sensor module has strong adaptability to ambient light. It has a pair of infrared transmitting and receiving tubes. The transmitting tube emits infrared rays of a certain frequency. 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, 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 to 30cm, and the working voltage is 3.3V-5V. The detection distance of the sensor can be adjusted by the potentiometer, and it has the characteristics of low interference, easy assembly, and easy use.It is widely used in many occasions such as robot obstacle avoidance, obstacle avoidance car, assembly line counting, and black and white line tracking.Parameter DescriptionSize: 32*14mmVoltage: 3.3-5VDistance Range: 2-30cm1 When the module detects the obstacle signal in front, the green indicator light on the circuit board lights up, and the OUT port continuously outputs a low-level signal. The module detects a distance of 2 to 30cm and a detection angle of 35°. The detection distance can be adjusted by the potentiometer. Adjust the potentiometer clockwise to increase the detection distance; adjust the potentiometer counterclockwise to reduce the detection distance.2. The sensor actively detects infrared reflection, so the reflectivity and shape of the target are the key to the detection distance. Among them, the black detection distance is the smallest, and the white is the largest; the distance of small-area objects is small, and the distance of large-area objects is large3. The output port OUT of the sensor module can be directly connected to the IO port of the microcontroller, or it can directly drive a 5V relay; connection method: VCC-VCC; GND-GND; OUT-IO4. The comparator uses LM393, which works stably5. The module can be powered by a 3-5V DC power supply. When the power is on, the red power indicator lights up6. It has 3mm screw holes for easy fixing and installation7. Each module has already adjusted the threshold comparison voltage through the potentiometer before delivery. Do not adjust the potentiometer at will unless there is a special situationInterface Description1 VCC External 3.3V-5V voltage (can be directly connected to 5v microcontroller and 3.3v microcontroller)2 GND External GND3 OUT Small board digital output interface (0 and 1)- Commodities include：10Pcs Photoelectric reflection sensor；10Pcs Male and Female Dupont Cable
