적외선 트랜스미터와 리시버를 장착하고 있으며, 발사된 적외선이 물체에 맞고 되돌아 오는 것을 리시버가 감지하여 장애물이 있는 것을 센싱하게 됩니다.
장애물이 있으면 초록 LED를 점등 시키고 디지털 신호(LOW)를 출력하게 됩니다.
보드상의 포텐셔미터를 이용하여 검출하고자하는 장애물의 거리를 조절할 수 있습니다.
동작가능한 효과적인 범위는 2-80cm 이며, 3.3V-5V와 동작합니다.
이동용 로봇이나 자동차에 사용하면 좋은 제품입니다.
특징
When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 80cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO
The comparator using LM393, stable;
3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit;
With the screw holes of 3mm, easy to install;
Board size: 3.1CM * 1.5CM
Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
Interface(3-wire)
VCC external 3.3V-5V voltage (can be directly connected with the a 5v microcontroller and 3.3v microcontroller)
