ABSTRACT
GSM Data Acquisition System is based on GSM Cellular Network. In this project we monitor the data in room by sending required data values to selected phone numbers using GSM modem. Data values are like functions of remotely data, environment monitoring (support input DC 0-20MA), fire protection, anti-burglary, as well as intelligent remote control. It is widely used in industry, building, petroleum, rail-way, school...etc.
Data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values that can be manipulated by a computer. Data acquisition systems (abbreviated with the acronym DAS or DAQ) typically convert analog waveforms into digital values for processing. Sensors convert physical parameters to electrical signals. Signal conditioning circuitry to convert sensor signals into a form that can be converted to digital values. Analog-to-digital converters convert conditioned sensor signals to digital values. Main Features of data acquisition systems are Data Monitoring, Fire Protection, Remotely Control Function, and Anti-burglary Function.
GSM Data Acquisition System can monitor the AC/DC voltage remotely. The user can know the exact data (e.g. input voltage is AC 220 V) via SMS; also user can set the voltage alarm point. When the input voltage is higher or lower this point, the system will alarm. It will send SMS, as well as phone call to inform user immediately.
1. AC Voltage input monitoring (Range: 0-500V).
2. Frequency input monitoring for AC signals (50Hz).
3. Temperature Monitoring (Range: -10 to +60).
