Home: This technology can be used to provide advanced temperature control, smart lighting and assist in the controllability or automation of innumerous other household functions including music and television controls etc. An example of this would be the embedding on a Zigbee radio in the electric meter and thermostat. This would enable the user to have the lights automatically turn off as the more expensive rates go on even if they are not at home. The consumer could of course override this if at home. Other uses in this area include the general monitoring of energy consumption in the home.

Home Security: This technology could be used to alert the consumer of smoke or intruders detected in their home.

Asset tracking: This technology can be used to track tagged assets to their exact location. Uses for this include company stock rooms, supermarkets where consumers can easily locate the section containing their desired products. This technology could also help users locate lost assets.

Commercial uses: Commercial applications include access control, energy monitoring and lighting, process control, machine-to-machine (M2M) communication and industrial device control.

Mobile uses: Mobile healthcare, which allows medical practitioners to bring up and verify correct information about their patients in real time and allows the real-time modification of information as required is an important use. Other mobile uses include monitoring and control, security and access control.

Monitoring Residential Wind Turbines

Small wind turbines are being deployed around the world to help reduce reliance on fossil fuel for the energy requirements of homes and businesses.Owners of the wind turbines need a way to monitor energy creation. Manufacturers need a way to monitor the health of the machine and to provide reporting services to government agencies to qualify for incentive programsTo do this, a manufacturer designed an Xbee ZigBee embedded module into its wind turbine. This 2.4 GHz radio module communicates to a ConnectPort X gateway inside the home or business that connects to the internet via the LAN. The ConnectPort X regularly communicates back to a central monitoring center at the manufacturer via an IP connection and the iDigi platform, giving the customer accurate energy creation data in real-time, and providing the manufacturer with any alerts to maintenance requirements of the turbine. In addition, it allows the manufacturer to make available energy creation data to interested government agencies, with the consent of the turbine owner.
Part of Digi’s Drop-in Networking product family, the Xbee, ConnectPort X and iDigi work together to allow wind turbine manufacturers todrop-in” a customized wireless network in a cost-efficient, non-intrusive, and secure manner. This solution offers significant benefits to the manufacturer and customers.
1) Customers may monitor energy creation in real-time, from anywhere.
2) Ability to remotely turn the turbine on/off if problems are detected
3) Ability for the manufacturer to proactively monitor the turbine for preventive Maintenance

XBee Helps Libelium Monitor Harsh Environments
Research and development team at Libelium (Zaragoza, Spain) is dedicated to developing hardware for the implementation of wireless sensor networks, mesh networks and communication protocols to monitor the environment around us, ranging from prevention of forest fires and floods to detecting and monitoring contamination levels in cities.
They needed radio frequency modules to guarantee accurate transmission of information from sensors placed in isolated or difficult-to-access areas. To enable Libelium to develop its sensor devices, they needed to source a wireless networking provider that offered both long-range links and the interconnection of wireless networks of different frequencies.
Using the XBee modules from Digi as the main communication radios, Libelium developed the Waspmote – a low-power wireless sensor capture, geo-localisation and communication device with high transmission power. Based on a modular architecture, Waspmote is able to detect a variety of parameters such as humidity, temperature, CO2 emissions, heartbeats and vibrations. Waspmote can be used in numerous industries including agriculture, environmental, logistics and security.
Their objective is to detect and store critical values and send these values to a data processing centre for analysis or send emergency alarms. Take the agricultural industry as an example. Waspmote sends a message through the ZigBee network when the sensors detect that the optimal level is reached in soil humidity. This contributes greatly towards efficient water management.
The Digi modules satisfy the unique needs of Libelium, providing low-cost and low-power wireless sensor networks. Designed to operate in harsh environments, the modules allow Libelium to network-enable sensor devices so that they can be monitored and controlled remotely. Libelium currently deploys the XBee and XBee-PRO 802.15.4 and DigiMesh® modules; XBee ZB modules; XBee XSC (900 Mhz) and XBee 868.
Waspmote is able to achieve long-range links of 7 km / 2.4 GHz, 24 km / 900 MHz and 40 km / 868 MHz, making it possible to monitor virtually any installation.
The long-range links are fundamental when monitoring delicate natural environments Infrared or ultraviolet sensors are used to detect flames, heat and gases that help identify the molecules of chemical compounds (CO and CO2) generated during combustion. A Waspmote sensor device can help to detect and prevent forest fires. Another example application is in the logistics field. Thanks to the Digi technology, shipping container conditions such as irregular temperatures and humidity levels, and whether the products have been contaminated or suffered an impact during transportation can be detected by Waspmote. This technology allows this information to be transmitted wirelessly.”

XBee Modules Reduce Hotels' Energy Cost

Lodging Technology installed its first beta wireless GEM Link system in April 2008. The GEM Link system consists of three parts: a Passive Infrared occupancy sensor mounted in the corner of a guest room; a Transceiver module connected to the HVAC unit; and the Entry/Patio door switch module mounted on the wall beside the door frame or on the door. Each component includes an XBee ZigBee module. The three components work in tandem to determine if a room is occupied and to adjust the ac/heat accordingly when a guest is not in the room.
When a guest enters a room outfitted with a GEM Link Wireless system, the door switch transmits to the HVAC Transceiver unit that the door is open via an XBee module. The infrared module then detects the heat of the guest in the room and transmits to the HVAC unit that someone is in the room also via an XBee module. When the door closes, control of the HVAC unit is released to the guest because it now knows someone is in the room and the door is closed. If there is a patio or balcony door, another wireless door switch can be added to that door as well.
