The sensor module has a strong ability to adapt to ambient light. It has a pair of infrared emission and receiving tubes. The emission tube launches a certain frequency infrared ray. When the detection direction meets an obstacle (reflector), the infrared reflection is received by the receiving tube. After the comparator circuit is processed, the green indicator lights up. At the same time, the signal output interface outputs a digital signal (a low level signal), and the detection distance can be adjusted by the potentiometer knob. The effective range is 2 to 30cm and the operating voltage is 3.3V-5V. The detection distance of the sensor can be adjusted by potentiometers, small interference, easy to assemble, easy to use and so on. It can be widely used in many occasions, such as robot obstacle avoidance, obstacle avoidance car, line counting and black and white line tracking.
Module parameter description
1 when the module detects the front obstacle signal, the green indicator light on the circuit board and the OUT port continuously output the low level signal. The module detects the distance 2 ~ 30cm, the detection angle is 35 degrees, the detection distance can be adjusted by the potentiometer, the clockwise potentiometer, the detection distance increase; the counter clockwise potentiometer. The detection distance is reduced.
2, sensor active infrared reflection detection, so the target reflectivity and shape is the key to detecting distance. Among them, the black detection distance is the smallest and the white is the largest.
3, the output port OUT of the sensor module can be directly connected with the microcontroller IO port, and can also directly drive a 5V relay. The connection mode: VCC-VCC; GND-GND; OUT-IO
4, the comparator adopts LM393, and the work is stable.
5, 3-5V DC power supply can be used to supply the module. When the power is connected, the red power indicator lights up.
6, with 3mm screw holes, easy to fix and install.
7. The size of the circuit board: 3.2CM*1.4CM
8, each module in the delivery of the threshold voltage has been adjusted through potentiometers, non special circumstances, do not adjust the potentiometer at will.
Module interface description
1 VCC external 3.3V-5V voltage (directly connected to 5V microcontroller and 3.3V microcontroller).
2 GND outside GND
3 OUT panel digital output interface (0 and 1)
