This sensor package is for line following Bot. Every now and then hobbyist who are willing to play with Line following Robot has tough time with the IR sensor arrangement. This is a neat solution for them.

Four TCRT5000 reflective optical sensors have been used here.The LM358 dual OPAMP works as a comparator with two reference voltages set by four POTs.The sensors have 0.5 inch spacing.

Calibration:To calibrate the sensors,you must tune the respective POTs.Connect VCC and GND pins with the power supply and connect SEN1 to SEN4 pins with four LEDs.Keep tuning the POTs until the LEDs glow.

Now,Draw a Black line on a white paper or vice versa.After the proper calibration is done,the LEDs will turn on when the sensors trace black and they will turn off when the Sensors trace white.That means,The output is always either 1(High) or 0(Low).

Q: I wanted to buy only these sensors. It was available a few months ago. But this time I couldn't find any. I want these -- Reflective Optical Sensor - TCRT5000 ROB-00022 Questioned by marufuddin, 30-Mar-2016

Q: please give a link about the assembly of this sensor Questioned by Nawshad, 06-Apr-2016

The product is already assembled. Connect +5V to Vcc and GND to GND. Now you can easily read the digital (1 or 0) output from the SEN1, SEN2, SEN3 and SEN4 pins. Answered by FAHIM_REAZA, 07-Apr-2016 12:12 PM
