Gorillacell Module 023: Line Detection Sensor
Table of Contents
The Line Finder Sensor, also known as a Line Detection Sensor, is a proximity sensor that detects objects or surfaces based on light reflection using an infrared transceiver. The IR transmitter emits infrared light, while the IR receiver measures the amount of light reflected back.
When the sensor passes over a dark surface (line), most of the infrared light is absorbed, resulting in less light being received. Conversely, when it passes over a light surface, most of the light is reflected, producing a stronger signal detected by the receiver.

PINOUT
It has 3 pins which are
- G - for the ground pin,
- V - for the supply voltage, and
- S - for determining the state of the Line Finder Sensor module.
A Line Finder Sensor produces a logic 1 when it detects a non-reflective surface (such as a black line) else it is logic 0 (reflective surface such as white).
Line Finder Sensor comes with a small trimmer resistor for adjusting the sensor sensitivity. Rotate it so that so that the LED D1 is not lit.
