Robomart Light Searching Sensor

It Consist Of Two Photodiode And An Lm358 Operational Amplifier Ic. The Intensity Level Of The Photodiodes Is Already Caliberated For Optimal Results For The Operational Amplifier. These Sensors Can Be Used In Applictions Where We Need To Use Light As A Medium.This Is A Light Based Digital Proximity Sensor. These Sensors Can Be Used To Sense Light In A Region. It Comes With Inbuilt Dual Operational Amplifier Ic That Converts The Analog Voltage Signal Into Digital Signal Making It Perfectly Suitable For Micro Controller / Processor Interfacing.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.Photo Diode / Ir Receiver : A Photodiode Is A Type Of Photo Detector Capable Of Converting Light Into Either Current Or Voltage, Depending Upon The Mode Of Operation. The Photo Diode Is Used As An Ir Receiver In This Device As It Is Used To Receive The Reflected Incoming Ir Rays.
