Wireless sensor data transfer using bluetooth technology

The objective of this thesis is to design and program an application for the Linux based Axis Etrax100LX developer board using the C programming language. This application will collect sensor data (4-20mA signals as the standard analog inputs and 0-5V as the digital inputs) from the serial port of the Etrax100LX developer board, save them to a file on the developer board and make this data available for remote access. The idea behind using the Etrax100LX development board and writing software for it is to build a wireless, web-based monitoring system for electrical and mechanical rotating machineray which makes the data available for remote access. Bluetooth is a wireless, data transmission technology [13] designed specifically for use in Personal Area Networks (PANs) where up to seven Bluetooth enabled computing devices such as Personal Computers and Personal Digital Assistants (PDAs) can form either a Group ad-hoc Network (GN or Bluetooth Piconet) or a network where one of them acts as a proxy, router or bridge (Network Access Point, NAP) between and existing network inftrastructure (typically LAN) and the other Bluetooth devices [14].
