4 Channel IR Array Sensor Line Tracking Module

Specification:

• Detection range: 1mm to 60 CM adjustable, the closer the performance more stable, white reflects the farthest distance.
• Size: in the control panel:4.2 x 3.8 x 1.2 cm (length x width x height).
• Small forward: 2.5 x 1.2 x 1.2 cm (length x width x height).
• Output interface: 6 wire interface (1234 to 4 signal output ends, + positive power, – for the negative power is ground)
• The output signal: TTL level.

This is a 4 Channel Infrared Tracing Module that provides an easy way for line tracking. A line sensor is composed of a number of cells and each cell is composed of a sender and a receiver. The particularity of this sender/receiver pair is that it sends light that shall be reflected by the line to be detected but not by the eventually opaque background surrounding this line. Any sender/receiver pair that is able to make a difference between a line and the rest of the ground (of a different color) can be used in a line sensor.

Following a line is one of the easiest ways for a robot to successfully and accurately navigate. It is a determined path, and good programming can ensure results that are far more consistent than if the robot was simply told where to go without any reference.
