Remote Data Acquisition of Physical Parameters Using Master-Slave Utility of Microcontroller

Improve the performance of remotely situated device control and data monitoring, acquisition with parameter such as temperature, pressure, vibration, humidity on real time basis give the data modularity as well as low data processing time. The infrastructure of the existing RF network is used, which is based on supervisory control, monitoring and data acquisition demands constant development and applicability in research. Versatile and highly accurate data acquisition system is investigated. In the present work, an embedded data acquisition system at operating frequency of 16 MHz is designed around the Atmega-16A microcontroller. The application of RF and microcontroller infrastructure is proposed. Wireless data acquisition deals with the creation of an inexpensive, adaptable and easy to use data acquisition within a network. The wireless data acquisition system, wh i c h i s setup the temperature, pressure and vibration monetring system with the precision readout, is designed using locally available electronics component. The necessary control have been dumped or embedded as software in the microcontroller to add the intelligence to the data accusation system sufficiently recorded from remote location and store in personal computer memory using hyper terminal utility. The designed system is compact, stand-alone, reliable, accurate and portable with on-board display of the acquired the data from remote place or system under observation. The properly designed Data Acquisition system saves time and money by eliminating the need of service personal to visit each site for inspection, data collection logging or make adjustments.
