Data acquisition and logging system
- 1. A PRE PRESENTATION ON DATA ACQUISITION AND LOGGING SYSTEM Project Guide Mr. Devi Prasad Pattnaik JITM Project Members Arpita Senapaty Khirod Kumar Maharana Monalisa Sahu Satish Kumar Sahu Department of Electronics & Communication Engineering JAGANNATH INSTITUTE FOR TECHNOLOGY AND MANAGEMENT
- 2. INTRODUCTION JITM Data acquisition is the process of sampling of real world physical conditions and conversion of the resulting samples into digital numeric values that can be manipulated by a computer. The process of using a processor to collect the data through sensors, analyze the data & save and output results of the collection and analysis.
- 3. EQUIPMENTS REQUIRED:- MICROCONTROLLER (AT89C51) TEMPERATURE SENSOR (LM35) AD CONVERTER (ADC 0808) SERIAL PORT INTERFACE (MAX232 ,RS 232) COMPUTER SYSTEM JITM

- 6. METHODOLOGY:- Methodology includes two things. 1.Signal Sensing 2.Data storing & Managing the System 1.Signal Sensing :- The physical state that to be measured is first to be transformed into unified form that can be sampled by a data acquisition system, called as Sensor. 2.Data Storing & Managing system :- Here the analog signal is converted to digital signal. Once digitized, the signal can be encoded to reduce and correct transmission errors. The corrected data are saved into a system for the future references. JITM
- 7. OBJECTIVES:- JITM To look back on past events and identify areas of interest and most of all saving cost and time. These events could assist in improving the following: • Efficiency • Performance • Accuracy • Reliability • Energy consumption
- 8. APPLICATION:- Weather station recording (such as wind speed / direction, temperature, relative humidity, solar radiation) Road traffic counting Wildlife research Tank level monitoring JITM
- 9. JITM Future Scope: - A Temperature Recorder for monitoring the performance of a heating and air conditioning system A Depth Recorder for tracking changes in the water table A flight data recorder (FDR), a piece of recording equipment used to collect specific aircraft performance data
