The infrared diode will emitting the infrared continuously when the module connect to the power, when the emitted infrared light has not been reflected or the strength is not big enough,the module will in the off state, at this time, D0 output logic HIGH and the signal indicate LED off. There is also an on-board potentiometer to adjust the sensitivity. The measuring distance range from 1mm to 8mm, and the central point is about 2.5mm. SnapEDA is a free online Proteus CAD library of symbols, decals (footprints), and 3D models for millions of electronic components. This sensor is often used in line following robots, auto data logging on utility meters, because this module can sense if a surface is white or black. It emits IR and then detects if it receives the echo. The data pins D4 to D7 are attached to Pins 5, 4, 3 and 2 of Arduino. Next step is LCD its RS and E pins are attached to Pins 7 and 6 of Arduino.

The OUT pin of the sensor is attached to Pin 11 of Arduino. This IR reflective sensor utilizes a TCRT5000 to detect color and distance. Arduino LCD POT Geared Wheel Circuit Diagram of LM393 IR Sensor First, attach the Vcc and GND of the Speed Sensor to 5v and GND of Arduino. These basic are showing you the analog and digital values at serial monitor. In this project, I have utilized a cheap Infrared Speed Sensor.

There are many kinds of Speed Sensor like Hall-effect sensors, Eddy Current speed sensor, etc. In this tutorial, we are going to teach you some basics on using TCRT5000 IR Sensor Module. A speed device could be a kind of measuring device that’s wont to calculate the speed of a revolving object sort of a motor.
