Many sophisticated electronic systems depends on transducers like temperature sensors, pressure sensors, vibration sensors, shock and strain gauge to measure the parameters in engineering units. ADC and DAC with support of high end microcontrollers will play a major role in data acquisition systems. The resolution of ADC will define the accuracy of the system. ADC with analog multiplexer will provide multiple channels to acquire pressure, temperature, vibration and shock. Most of the pressure channels will provide DC voltage from 0 to +5v range full scale. The selected ADC with highly stable reference voltage, the signal conditioner and a low pass filter to suppress the noise will make full fledged data acquisition channel for measurement of pressure in Bar. High end microcontroller ADuC7026 with built in 12 ADC, 4 ADC/DAC, set of timers, general purpose I/O’s and UART will provide accurate results to design multichannel data acquisition systems. Now a day’s microcontrollers with built in ADC and DAC’s, timers, UART’s are available to make system very small and compact. One can develop embedded software to suit the system requirement with well defined communication protocol with user defined sampling rates. Data will be provided on RS-232 interface to application software. Where, pressure data will be displayed in tables with time stamp. Application (GUI) will be provided with a set of plots and graphs, where user can visualize the pressure data in engineering units. Data can be logged into excel sheets for feature reference. Advance microcontrollers and application software makes realization of data acquisition system with high degree of accuracy and ease.
