Microcontroller Based Data Acquisition System

Data acquisition systems (DAS) are the basis for building monitoring tools that enable supervision of local and remote systems. The present paper describes the design of a cost effective, better resolution DAS which is compatible to most of the PC and laptops. A low cost DAS has been designed using Atmega8 Microcontroller. A suitable Graphical user interface (GUI) is generated by using a Visual Basic program connected to a homemade data converter board using the AVR microcontroller.
