DFRobot Adjustable Infrared Sensor Switch

The DFRobot Adjustable Infrared Sensor Switch is a set of transmitter and receiver in one of the

photoelectric switch sensor. The detection distance can be adjusted according to the demand. The

sensor has a detection range of 3-80cm. The DFRobot Adjustable Infrared Sensor Switch is small, easy to

use, inexpensive, easy to assemble and can be widely used in robot to avoid obstacles, interactive

media, industrial assembly line, and many other occasions. The switching signal output differs in

accordance to the obstacles. It remains high when no obstacles and remains low when there are

obstacles. There is a bright light behind the probe to detect the scope of 3cm - 80cm.

Specification:

Adjustable detection range, 3cm - 80cm

Small, easy to use/assemble, inexpensive

Useful for robot, interactive media, industrial assembly line, etc

Power supply: 5V

Pinout:

Red - V+

Yellow - Signal

Green - GND
