The use of sensors is very widespread in a lot of different environments and applications. Each situation needs a different solution and for that reason the use of a scalable and easily manageable sensor network is a must as applications are becoming increasingly complex. In many cases the perfect solution is the one based on a wireless sensor network; it provides flexibility, ease of management of the system and expandability. But in order to provide interoperability between different sensor manufacturers and to give a transparent and independent interface, the use of a standard is mandatory. This standard system is provided by the IEEE 1451 family of standard protocols. In this project a Bluetooth based sensor network has been implemented using the IEEE 1451 family of standard protocols. The goal of this network is to aid data acquisition from a number of sensors within a car, in order to monitor the wellbeing of the passengers and improve safety and comfort.
