IR Infrared Obstacle Detaction Sensor Module 2 - 30cm


The basic concept of IR(infrared) obstacle detection is to transmit the IR signal(radiation) in a direction and  a signal is received  at the IR receiver when the IR radiation bounces back from a surface of the object.
Features:
    There is an obstacle, the green indicator light on the circuit board
    Digital output signal

    Detection angle: 35 ° Degree
    Comparator chip: LM393
    Adjustable detection distance range via potentiometer:
        Clockwise: Increase detection distance
        Counter-clockwise: Reduce detection distance
Specifications:
    Working voltage: 3 - 5V DC
    Output type: Digital switching output (0 and 1)
    3mm screw holes for easy mounting
    Board size: 3.2 x 1.4cm
