Design of PIC microcontroller-based data acquisition module with lab VIEW interfacing

Using Microchip´s Peripheral Interface Controller (PIC) microcontroller and the Current Transducer (CT), we have designed data acquisition module (DAQ). The present paper describes the design of a cost effective, better resolution, simple structure and high reliability features. Data acquisition system is compatible to most of the PC and laptops and its design is interfaced to the serial port of the PC in which data converted and passed on to the computer. Laboratory Virtual Instrument Engineering Workbench (Lab VIEW) application on the computer acquires the data and plots on the appropriate graph and indicators of respective transducers.
