INFRARED IR PROXIMITY SENSOR MODULE FOR ARDUINO RASPBERRY Pi

2, the sensor active infrared reflection detection, target reflectivity and so the shape is critical detection distance. Where the minimum detection distance is black, white, maximum; small objects away from a small area, a large area of ​​the Grand.

3, the output port of the sensor module OUT port can be directly connected to the microcontroller IO can also directly control a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO

4, comparators LM393, stable;

5, the module can be 3-5V DC power supply. When the power is on, the red power indicator lights up;

6, with the screw holes 3mm, easy fixed installation;

7, board size: 3.2CM * 1.4CM

8, each module is sent threshold comparator voltage adjusted by potentiometer well, non-special case, not adjustable potentiometer.

Module Interface Description

1 VCC 3.3V-5V external voltage (can be directly connected to 5v and 3.3v MCU MCU)

2 GND External GND

3 OUT the small board digital output interface (0 and 1)When the module detects an obstacle to the signal, the green indicator lights up at the board level, while the OUT port kept a low signal output, the module detects the distance 2 ~ 30cm, detection angle 35°, the distance can detect the potential, is with clockwise adjusted adjustment potentiometer, detects the distance increases; Potentiometer counterclockwise, reducing detection distance.
