Module Description:
The sensor module has strong adaptability to ambient light. It has a pair of infrared transmitting tubes and receiving tubes. The transmitting tube emits infrared light of a certain frequency. When the detection direction encounters obstacles (reflecting surface), the infrared light is reflected back to be received by the receiving tube. After being processed by the circuit of the comparison device, green means that the color light is on. At the same time, the signal output interface outputs digital signals (low-level signals). The detection distance can be adjusted through the potentiometer knob, The effective distance range is 2-30cm, and the working voltage is 3.3V-5V. The detection range of the sensor is adjusted by a potentiometer, which has the characteristics of small interference, easy assembly and easy use. It can be widely used in robots, obstacle avoidance vehicles, line counting, black and white lines and other occasions.
Module parameter description:
1 When the module detects the signal of obstacles in front, the green light on the board level lights up, and the OUT port outputs a low-level signal. The detection distance of the module is 2~30cm, and the detection angle is 35 °. The detection range can be adjusted by the potentiometer, and the potentiometer can be adjusted clockwise. The detection range increases, and the potentiometer can be adjusted counterclockwise, and the detection range decreases.
2. The reflectivity and shape of the target detection range are crucial for reflective active infrared sensor detection. Black detects distance, while white detects most small objects from small and large distances.
3. The sensor output OUT can be directly connected to the microcontroller IO port, or it can drive a 5V Relay connection: VCC-VCC; GND-GND; OUT-IO
4. Comparator LM393, stable;
5. You can use a 3-5 V DC power supply to power the module. When the power is turned on, the red power indicator light lights up;
6. Equipped with 3mm screws for easy fixing and installation;
7. Plate size: 3.2CM * 1.4CM
8. The threshold voltage of each module is adjusted by the potentiometer when it leaves the factory, and it is not necessary to adjust the potentiometer unless it is under special circumstances.
Module interface description:
1. External 3.3V-5V 1 VCC voltage (5V microcontroller directly connected to 3.3V microcontroller)
2. GND External GND
3. OUT small board digital output interface (0 and 1)
