The present paper describes the design of a cost effective, better resolution data acquisition
system (DAS) which is compatible to most of the PC and laptops. A low cost DAS has been designed
using PIC12F675 having 4-channel analog input with 10-bit resolution for the monitoring of slowly
varying signals. The DAS so designed is interfaced to the serial port of the PC. Firmware is written in
Basic using Oshonsoft PIC IDE and burn to the microcontroller by using PICkit2 programmer. An
application program is also developed using Visual Basic 6 which allows to display the waveform of
the signal(s) and simultaneously the data also can be saved into the hard disk of the computer for
future use and analysis.
