Robomart IR Based Digital 5 Sensor Array  (Red)

It'S An Ir Based Proximity Sensor Array That Provides 5 Bit Of Digital Output Based On The Surface Sensed By The Sensors. The Array Is A Group Of 5 Ir Sensors Which Sense Precisely The Changes And Provides A Perfectly Diffrentiable Input Values For Constructing An Intelligent Robot. These Sensors Are Best Suited For Grid Solving Robots And Have Many More Applications Like Selecting Paths, Avoiding Edges, Sensing Obstacle, Etc. Operational Amplifier : An Operational Amplifier (Op - Amp) Is A Dc - Coupled High - Gain Electronic Voltage Amplifier With A Differential Input And, Usually, A Single - Ended Output. In This Device It Has Been Used As A Comparator. The Use Of Comparator Makes The Device As A Digital Device Since It Converts The Incoming Signal From The Photo Diode Into Digital One. Or We Can Simply Say The Incoming Signals Are Amplified To Vcc. Ir Led : An Ir Led, Also Known As Ir Transmitter, Is A Special Purpose Led That Transmits Infrared Rays In The Range Of 760 Nm Wavelength. Such Leds Are Usually Made Of Gallium Arsenide Or Aluminum Gallium Arsenide. They, Along With Ir Receivers, Are Commonly Used As Sensors.
