Steps towards a minimal mobile wireless BluetoothTM sensor

This paper describes a new Bluetooth^TM-based wireless implementation of a mobile sensor. The solution reduces dramatically both power consumption and size of a wireless sensor improving earlier Bluetooth^TM implementations where multi-chip solutions were used and mobility was not supported. Three different implementations from multi-chip to single chip are described with the sensor wireless interface, the architecture, protocols and algorithms used. Achieved results are: (1) Implementation of 1 chip solution wireless sensor using the internal Bluetooth^TM module ADC for external sensing purposes. (2) Mobile sensor wireless monitoring with Bluetooth^TM.
