Infrared Barrier Module/Car Obstacle Avoidance Sensors Black Line Identification Adjustable Distance EDC-422157

Rs. 1.50

Product Features:

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
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
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
The comparator using LM393, job stability
Can be 3-5V power supply for the module . When the power is turned on, the red power indicator light ;
With 3mm screw holes for easy mounting, installation
The circuit board size : 3.1CM * 1.5CM
Each module is shipped already comparing the threshold voltage adjustable via potentiometer good, non-exceptional circumstances , do not arbitrarily adjust the potentiometer
