Eight Channel Data Acquisition System Abstract


      The main of  EIGHT CHANNEL DATA ACQUISITION SYSTEM project is to capture data (Analog) from sensors and display on PC.

This application uses 8051 micro controller with a 8 bit analog to digital converter. And the out put is displayed on LCD screen.

A characteristic feature of A to D converters is its resolution; another important feature is the conversion speed.Higher the resolution more the number of bits required to represent the data. The digital data from the A to D chip becomes available when the chip indicates end of conversion. The A to D chip requires a clock for producing the conversion. An 8 bit ADC can produce a count of 255 for full scale. I.e. if the full scale (5V) then 5/255 will be the least value that the A to D can measure. This is called 1LSB. This value multiplied by the port data produces the voltage at the analog input of the chip. Another important aspect of any A to D conversion is the analog ref. Voltage supplied to the chip. The accuracy of this voltage dictates the accuracy of the reading.
