Low Cost Data Acquisition and Control System Based on Single Chip

Abstract

The advance technological, the processes monitoring are becoming more complex with increase in, efficient, analysis of process, number of parameters under data acquisition with single chip environment is increases . New generation data acquisition developments have been emerge with controlling and monitoring with microcontroller technology, which enables real-time data collection, analysis, logging and plotting of data. The requirements the demand of an improved, efficient and up- to-date data logger is increasing, with combination of a sensor, microcontroller, and a data storage device. Data loggers are provided with real time record and time of acquisition. In this paper, a data logger prototype is designed and tested for the specific application as pressure, temperature and vibration. The system works around the AT-MEGA-16 microcontroller. The system is designed and developed to measure temperature, vibration and pressure with accurate sensors and the result is stored in memory such as EEPROM for post process analysis. During the testing, it is verified that there is real time correct data acquire and stored in memory. Using a LCD display verified the current data storage. The focus of design is on portability and low power consumption in robust environment.
