5mm Infrared sensor

Description

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 distance: 2 ~ 30cm Detection angle: 35 ° Degree Comparator chip: LM393 Adjustable detection distance range via potentiometer: -Clockwise: Increase detection distance -Counter-clockwise: Reduce detection distance
