SmartElex RLS05 is Line follower sensor module used to detect the Line. SmartElex RLS05 consists of 5 arrays TCRT5000 IR transmitter and IR receiver pairs.

Line Follower Robot is a machine which follows a line, eithera black line or white line. Basically, there are two types of line follower robots: one is black line follower which follows the black line and second is white line follower which follows the white line.

The paramount of this Line Follower Robot is the IR Sensor and Detector(Photoresistor/Photodiode) which actually senses the line and run over it.

The concept of working of line follower sensor is related to light. We use here the behavior of light at the black and white surface. When light fall on a white surface it is almost fully reflected and in case of black surface light is completely absorbed. This behavior of light is used in building a line follower sensor.
