Steps towards a minimal mobile wireless Bluetooth/sup TM/ sensor

Abstract

This paper describes a new Bluetooth/sup TM/-based wireless implementation of a mobile sensor. The solution reduces dramatically both power consumption and size of a wireless sensor improving earlier Bluetooth/sup 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/sup TM/ module ADC for external sensing purposes. (2) Mobile sensor wireless monitoring with Bluetooth/sup TM/.
