โมดูลเซนเซอร์ 3 PIN IR Infrared Obstacle Avoidance สำหรับ Arduino

Smart Car Robot Reflective Photoelectric 3pin IR Infrared Obstacle Avoidance Sensor Module for arduino Diy Kit Two modules Parameter Description When the module detects an obstacle in front of the signal , the circuit board green indicator light levels while continuing output low signal OUT port , the module detects the distance 2 ~ 60cm, detection angle 35 °, the distance can detect potential control to adjust, adjust potentiometer clockwise , the detection distance increases ; counterclockwise adjustment potentiometer, detection distance decreases. 2, the sensor active infrared reflection survey , so the target reflectivity and shape of the detection range of the key. The minimum detection distance which black and white max ; small area of the object distance is small , a large area from the Grand . 3 , the sensor module output port OUT can be directly connected to the microcontroller IO port , but also can directly drive a 5V relay ; Connection : VCC-VCC; GND-GND; OUT-IO 4 , the comparator using LM393, job stability ; 5 , can be 3-5V DC power supply for the module . When the power is turned on, the red power indicator light ; 6, with 3mm screw holes for easy mounting, installation ; 7 , the circuit board size : 3.1CM * 1.5CM 8 , each module is shipped already comparing the threshold voltage adjustable via potentiometer good, non-exceptional circumstances , do not arbitrarily adjust the potentiometer. Three module interface specification ( 3-wire ) 1 VCC external 3.3V-5V voltage ( 5v microcontroller and can be directly connected to 3.3v MCU ) External GND 2 GND 3 OUT small board digital output interfaces ( 0 and 1 ) Four shipping list A sensor module shown a barrier 2 20cm DuPont line 3 easy connection #Sensor #Module #Arduino
