Description:
1. The sensor module has strong adaptability to environmental light. It has a pair of infrared transmitters and receivers. The transmitter emits a certain frequency of infrared rays.
2. When the detection direction encounters obstacles (reflecting surface), the infrared rays are reflected back and received by the receiver. After processing by the comparator circuit, the green indicator lights up, and the signal output interface outputs digital signals (a low-level signal).
3. The detection distance can be adjusted by potentiometer knob. The effective range is 2-30cm and the working voltage is 3.3V-5V.
4. The detection distance of the sensor can be adjusted by potentiometer, which has the characteristics of small interference, easy assembly and easy use.
5. It can be widely used in many occasions, such as obstacle avoidance of robots, obstacle avoidance car, pipeline counting and black-and-white line tracing.

Feature:
1. When the module detects the obstacle signal in front, the green indicator lights up the level on the circuit board, and the OUT port continuously outputs low-level signal. The module detects the distance from 2 to 30 cm, and the detection angle is 35 degrees.
2. The detection distance can be adjusted by potentiometer. The detection distance can be increased by clockwise potentiometer; the detection distance can be reduced by counter-clockwise potentiometer.
3. Sensor active infrared reflection detection, so the reflectance and shape of the target is the key to the detection distance. Among them, the black detection distance is the smallest and the white is the largest, while the small area objects have the smaller distance and the large area objects have the larger distance.
4. Output port OUT of sensor module can be directly connected with IO port of single chip computer, or can directly drive a 5V relay; Connection mode: VCC-VCC; GND-GND; OUT-IO.
5. Comparator uses LM393, which works stably.
6. The module can be powered by 3-5V DC power supply. When the power is connected, the red power indicator lights up.
7. It has 3 mm screw hole, which is easy to fix and install.
8. The threshold comparative voltage of each module has been adjusted by potentiometer in shipment. Do not adjust potentiometer at will unless special circumstances arise.
