Wireless Sensor Based on Bluetooth Technology


This document discusses a project which aimed of building a wireless sensor device. The objective of the project is to master a new sensor approach. Target applications are robotic systems including medical robots. This project is decomposed in two phases. These two phases are reported in the main parts of this document (overview and proof-of-concept prototype). The first phase deals with concept and general architecture. The following actions take place:     We present target applications, and the kind of sensor that can be used in them.      Existing similar research projects were investigated: Usually, documents related to these projects are open documents. That means that one has an idea about how work has been done, and what can be done (limits) in terms of technology. The drawbacks are that final products do not exist or that they are not described in any document.      We investigated also off-the-shelf (commercial) wireless sensors: This class of information is useful to know what is reachable in terms of final products. However, you do not know how company did it: the "Commercial product"term implies usually a secret process.     We list the electronic modules, which can be candidate for a wireless sensor device. That implies RF (Radio Frequency) modules, micro controller modules, energy technology, and sensor devices.     We report uncertainties about technology and functionality that should be cleared up within a prototype project. The second phase is related to a proof-of-concept prototype. The goal of this prototype is to know if the concept, as defined during the first phase, works in real. We report how we successfully built a wireless sensor. Aspects presented are as follows: About the test bed itself: specification, hardware description, embedded software, purchased list and cost, are given. About the development environment: tools for programming and debugging the test bed, and experiments per-formed are described. We report also the experiments results and discuss the prototype. Off-the-shelf modules have been bought when existing. We tested the concept by using a dual axis inclination sensor. We chose this sensor because we had a previous experience with it. When designing the test bed, we tried, as much as possible, to get close to a usable product. Therefore, we took care of the sensor dimensions, the power consumption, etc.
