Modul ini biasanya digunakan untuk menghindari halangan/obstacle pada mobile robot dengan memanfaatkan prinsip kerja dari Infrared,
Module Parameter Description
1 When the module detects obstacles in front of the signal, the green indicator lights on the board level, while the OUT port sustained low signal output, the module detection distance 2 ~ 30cm, detection angle 35 , the detection distance can be potential is adjusted clockwise adjustment potentiometer, detects the distance increases; counterclockwise adjustment potentiometer, reduce the detection distance.
2, active infrared reflective sensor detection, so the target reflectivity and shape is the key to the detection distance. Wherein the minimum detection distance black, white maximum; small objects away from a small area, a large area from the great.
3, the sensor module output port OUT port can be directly connected to the microcontroller IO can be directly drive a 5V relay; connections: VCC-VCC; GND-GND; OUT-IO
4, comparators LM393, stable;
5, can be used for 3-5V DC power supply modules. When the power is turned on, the red power indicator light;
6, with screw holes 3mm, easy fixed installation;
7, circuit board size: 3.2CM * 1.4CM
8, each module has been shipped comparison voltage threshold adjusted by potentiometer good, non-special case, do not adjustable potentiometer.
Module Interfaces
1 VCC 3.3V-5V external voltage (which can be directly connected with 5v and 3.3v MCU MCU)
2 GND External GND
3 OUT small board digital output interface (0 and 1)
