Usefulness of Silicon Technology in Smart Sensor
There are very convincing advantages of using silicon technology in the construction of smart sensor. All integrated circuits employ silicon technology. A smart sensor is made with the same technology as integrated circuits. A smart sensor utilizes the transduction properties of one class of materials and electronic properties of silicon (GaAs). A transduction element either includes thin metal films, zinc oxide and polymeric films. Integrating electronics circuits on the sensor chip makes it possible to have single chip solution. Integrated sensors provide significant advantages in terms of overall size and the ability to use small signals from the transduction element [1]. The IC industry will get involved in smart sensor if a very large market can be captured and the production of smart sensor does not require non-standard processing steps.
Bluetooth Sensor Development Kit
Smart Sensor Systems’ Bluetooth Sensor Development Kitprovides the hardware and software needed to integrate yourtransducer (sensor or actuator) into a Bluetooth wireles
ssensor network that complies with the IEEE 1451 standard. Inthe nomenclature of IEEE 1451, the transducer is known as theTransducer Interface Module (TIM) while the sensor networkcontroller is known as the Network Capable ApplicationProcessor (NCAP). These are shown in Figure 1.

These are shown in Figure 1.The Bluetooth Sensor Development Kit allows you to develop awireless, IEEE 1451-compliant TIM that uses your sensor oractuator hardware. Your TIM will benefit from the manyfeatures of IEEE 1451 like Plug & Play, automatic sensor errorcorrection, ease of sensor network installation, and simplifiedsensor replacement to name a few.
Furthermore, you’ll be able to wirelessly connect up to sevenBluetooth TIMs to a single NCAP at distances up to 30 meters.Figure 2 illustrates this Bluetooth wireless sensor system.
The design of the Bluetooth Sensor DevelopmentKit is focused on minimizing the effort for sensormanufacturers to either convert existing sensors tobe IEEE 1451 compliant or develop new sensorsthat are IEEE 1451 compliant. Smart SensorSystems has developed the IEEE 1451 softwarestack that you’ll need for the TIM along with thedriver software to interface to the
Bluetoothtransceiver. Also included in the Development Kitis a high-resolution A/D converter and abreadboarding area where you can add your ownsensor hardware and any signal conditioning thatyou require. The A/D converter input subroutinessupplied with the Development Kit make it straightforward to integrate your sensor hardware into the TIM.
On the NCAP side, the
Development Kit provides a second Bluetooth transceiver and a sufficient subset of the IEEE1451 software stack to allow you to validate operation of your TIM. Also provided with the NCAP is a simple GUI thatallows you to exercise your TIM.Smart Sensor Systems’ flexible and modular TIM design makes it straightforward to transition from a TIMdevelopment environment to a TIM production environment. In fact, it’s possible to deploy Bluetooth-based TIMs inproduction that are based on the exact same set of boards that are used in the Bluetooth Sensor Development Kit.To understand how this is achieved, we’ll first look at Smart Sensor Systems’ TIM architecture.

Adaptive Sensor Network Architecture
Sensor networks have emerged as a promising tool for monitoring (and possibly actuating) the physical world, utilizing self-organizing networks of battery-powered wireless sensors that can sense, process and communicate. In sensor networks, energy is a critical resource, while applications exhibit a limited set of characteristics. Thus, there is both a need and an opportunity to optimize the network architecture for the applications in order to minimize resource consumed. The requirements and limitations of sensor networks make their architecture and protocols both challenging and divergent from the needs of traditional Internet architecture.
