Turning nodes into a network requires a device for sending and receiving information over a wireless channel.

The actual interface to the physical world; devices that can observe or control physical parameters of the environment.

Some memory to store programs and intermediate data, usually, different types of memory are used for programs and data.

A controller to process all the relevant datal capable of executing arbitrary code.

Where a sensor user can store date regarding the sensors location, next calibration date.

An area that has yet to be fully defined by the IEEE1451.4 committee but will likely contain additional data that is distinct for each class of sensor and will be complied by the manufacturer.

Where all the electrical and physical properties are stored.

The IEEE1451.4 committee has only published a draft specification. All indications are that the standard will change slightly before it is published in its final format. National Instruments and its sensors partners have decided not to wait for final…

IEEE 1451.4 directs its attention to only the TEDS part of the sensor and signal conditioning system. IEEE 1451.4 adopts a valuable approach by taking a much more simple approach to other smart sensor concepts by simply focusing on the self-identification…

The first of these standards was IEEE1451.2. The standard was designed to gain a standard way to specify the device operation and calibration, a standard physical interface between the sensor and the communication device, and the ability to use standardized…

A set of standards that were established to address smart sensor systems and to develop a comprehensive set of sensor and software protocols. It was hoped that the standard would pave the way for seamless connection of many parts of smart sensors and…

While the IEEE802.15.4 standard specifies a communication architecture that is appropriate for wireless sensor networks, it stops short of defining specifics about the sensor interface. The IEE1451.5 wireless sensor working group aims to build on the…

The ZigBee Alliance is an association of companies working together to enable reliable, cost-effective, low-power ,wirelessly networked monitoring and control products bases on a open global standard. The ZigBee alliance specifies the IEEE 802.15.4 as…

The standard was specifically designed for the requirements of wireless sensing applications. The standard is flexible, as it specifies multiple data rates and multiple transmission frequencies. The power requirements are moderately low; however, the…

A personal area network (PAN) standard that is lower power than 802.11. It was originally specified to serve applications such as data transfer from personal computers to peripheral devices such as cell phones or personal digital assistants. Bluetooth…

A standard that is meant for local are networking for relatively high bandwidth data transfer between computers or other devices. The data transfer ranges from as low as 1 Mbps to over 50Mbps. Typical transfer rate is 300 feet wit ha standard antennal…

Defines the operating frequency, modulation scheme, and hardware interface of the radio to the system.

A hybrid between the star and the mesh network provides for a robust and versatile communications network, while maintaining the ability to keep the wireless sensor nodes power consumption to a minimum.

A mesh network allows for any node in the network to transmit to any other node in the network that is within its radio transmission range.

A communications topology where a single base station can send and/or receive a message to a number of remote nodes. The remote nodes can send and/or receive a message from the single base station; they are not permitted to send messages to each other…
