Robomart A/D Sensor Module

A/D Converters - Are Widely Used By Many Engineers And Scientists Of All Types, Often Without Their Realizing It. Whenever They Make A Measurement Of A Voltage, And That Measurement Is Taken Into A Computer, An A/D Is Used. Analog To Digital Converters Are Among The Most Widely Used Devices For Data Acquisition. Digital Computers Use Binary Values, But In The Physical World Everything Is Analog (Continuous).Temperature, Pressure, Humidity And Velocity Are A Few Examples Of Physical Quantities That We Deal With Every Day. The Input To An Analog-To-Digitalconverter (Adc) Consists Of A Voltage That Varies Among A Theoretically Infinite Number Of Values. Examples Are Sine Waves, The Waveforms Representing Human Speech, And The Signals From A Conventional Television Camera. The Output Of The Adc, In Contrast, Has Defined Levels Or States. The Number Of States Is Almost Always A Power Of Two -- That Is, 2, 4, 8, 16, Etc. The Simplest Digital Signals Have Only Two States, And Are Called Binary. All Whole Numbers Can Be Represented In Binary Form As Strings Of Ones And Zeros.Digital Signals Propagate More Efficiently Than Analog Signals, Largely Because Digital Impulses, Which Are Well-Defined And Orderly, Are Easier For Electronic Circuits To Distinguish From Noise, Which Is Chaotic. This Is The Chief Advantage Of Digital Modes In Communications. Computers "Talk" And "Think" In Terms Of Binary Digital Data; While A Microprocessor Can Analyze Analog Data, It Must Be Converted Into Digital Form For The Computer To Make Sense Of It.Features:-? Low Cost? Work On 5v Voltage Power Supply? Provide Data In Digital As Well As In Analog Form? It Will Connect Almost All Type Of Analog Sensors
