Web-based Data Logger

Thanks to the World Wide Web, a new paradigm has been born. Any test facilities can now be configured to use a Web-based test logger, enabling worldwide participation in tests. A Web-based test logger for automatically writes selected test and facility parameters to a browser and allows researchers to insert comments. All data can be viewed in real time via Internet connections, so anyone with a Web browser and the correct URL (universal resource locator, or Web address) can interactively participate. As the test proceeds and data are taken, Web browsers connected to the logger are updated automatically. Welcome to the age of worldwide research with worldwide participation.

Basic Idea is to transmit the data from one point to another, this transmission may be wireless or with wire over the internet, is more enhance technology than with-wire transmission so we adopted wireless transmitting and receiving data. 4 types of data is transmitted by different types of sensors. They include Temperature sensor, Fuel level Sensor, Pressure sensor and rpm sensor. These all sensors have analog output in the form of voltages so we have to convert it into digital data then we will able to transmit.  Well we converted analog data into digital data. Why? Because four different types of data are being transmitted trough one channel so multiplexing is required. Due to this we used a digital switch which multiplexed the four data and convert it into digital form one by one.
