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, either a 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.
SmartElex RLS05 have 5 analog and digital outputs to the user indicating the presence of the line. The user can use both analog and/or digital signal. Each Sensor has its own LED as an indication of line detection. Each sensor on SmartElex RLS05 is independent of each other.
SmartElex RLS05 has a manual calibration button. The calibration button is multifunctional. SmartElex RLS05 also have SPI and Serial communication Pins. By this communication protocol, we can get the data of IR output values.
HOW TO CALIBRATE?
RLS05 need to be calibrated to save the black and white value of the surface that it will do the line follow. SmartElex RLS05 save values in EEPROM. Hence, only one-time calibration is needed for the same surface and line.
Step 1: Entering into Calibration Mode
To calibrate RSLS05, simply press the calibration button once or pulling down the Cal. for few milliseconds. Three LED’s (D0-D2-D4) turns ON means it entered in calibration mode.
Step 2: White surface reading
Here you have to place the RLS05 Module on a white surface to read the values. By pressing the calibration button one more time, two led turn ON (D3-D4) means it read and saved the white surface data in EEPROM.
Step 3: Black surface Reading
Now it ready to read black surface value, so you have place module on a black surface. Press the calibration button one more time three led turns ON (D2-D3-D4) to indicate that it read and saved the black surface value.
Step 4: Selection of White or Blackline Tracing
Now you have to decide whether SmartElex RLS05 follows the black line follower or white line follower. To enter into the white line follower you need to press calibration three time’s within the second. When you pressed here calibration thrice within second three led blinks (D2-D3-D4) for few times to indicate that module ready for the white line follower. For black line follower, you need to press the calibration button two times which will enter into the black line follower. It indicated by three led blinks (D0-D1-D2) for few times.
