Supplier: Techshop Bangladesh

 

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


Two LTH-1550 reflective object sensors have been used here. The LM358 dual OPAMP works as a comparator with two reference voltages set by two POTs.The sensors have 0.5-inch spacing.

 

Calibration: To calibrate the sensors, you must tune the respective POTs.The left POT is connected to SEN1 and the right POT is connected to SEN2. Connect VCC and GND pins with the power supply and connect SEN1 and SEN2 pins with two LEDs.Keep tuning the POTs until the LEDs glow.


Now, draw a Black line on 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) just as the word 'digital' indicates.

Q: can i connect it's outpin to L293D IC? Questioned by saqib11, 18-Nov-2015

May We know why should you connect it to L293D???? This is a SENSOR which should be connected to MCU so that the MCU can take input and make decision. Answered by A.R, 19-Nov-2015 03:40 AM

Q: I want to make a line following robot .......and it a analog circuit that's why.....The circuit is based on L293D IC Questioned by saqib11, 20-Nov-2015

L293D has 4 Inputs. This one has 2 outputs. So, no it will not complete your circuit. Answered by A.R, 22-Nov-2015 03:57 AM

Q: recently I've purchased this module from u. My purpose is different. I need slightly better range. What modification I have to do? Questioned by bobseee, 09-Aug-2016

Dear customer, For maximum range of detection, you can use "IR Infrared Obstacle Sensor". It may solve your purpose. Link: https://www.techshopbd.com/product-categories/sensors/1824/ir-infrared-obstacle-sensor-techshop-bangladesh Answered by FAHIM_REAZA, 11-Aug-2016 03:29 AM
