Hitachi WirelessInfo's AirSense Manages Work Environments

BOSTON /BUSINESS WIRE/ -- A new real-time monitoring system from Hitachi WirelessInfo is helping companies create controlled environments where temperature, humidity, and airborne particles can be managed to maintain ideal working conditions. The new Hitachi AirSense system, based on Ember's ZigBee wireless networking technology, will be a boon to food production plants, healthcare facilities, warehouses, and other buildings where precise air and ambient control is critical to operations.

AirSense enables companies to more easily improve the sanitary, safety, and quality conditions of their work environments. Consider, for example, a cheese manufacturer or beer brewer who must maintain precise temperature and humidity controls during fermentation while also controlling airborne yeasts that might contaminate their product; or a hospital burn ward, where temperature control and protection against airborne infectious pathogens can save lives. In these applications, AirSense "ZigBee-enables" devices—such as thermometers, hygrometers, and particle sensors—along with environmental controls, to create a self-forming monitoring network. More than 50 companies have already deployed AirSense since its debut in December 2005.

"Hitachi WirelessInfo's AirSense is another great example of how ZigBee wireless technology is being used in real commercial products to solve important problems today," said Robert LeFort, Ember's president and CEO. "Hitachi's adoption of Ember's ZigBee platform is strong validation of a standards-based approach to commercial wireless sensing and control applications."

Companies can easily install AirSense networks wirelessly using a range of fixed and portable sensor nodes. The nodes automatically self-organize into low-power wireless mesh networks and can run for up to four years on inexpensive batteries. The system also includes AirSense-Ware, a network management application for configuring and controlling large scale AirSense networks.

AirSense is based on Ember's EM2420 ZigBee semiconductor system and EmberZNet ZigBee-compliant networking stack. Hitachi WirelessInfo, a new division of Hitachi, Ltd., formed last year, plans to port its AirSense application to Ember's EM250 ZigBee system-on-a-chip for its next-generation product. The company is also working on extending AirSense to other applications, such as building automation, office security, and asset tracking.

"Hitachi's AirSense products utilize Ember's proven ZigBee technology so that our customers can experience the benefits of a low-power, wireless, and maintenance-free network," said Taizo Kinoshita, president and CEO of Hitachi WirelessInfo. "The partnership with Ember is essential to our strategy to commercialize sensor network systems, as well as promote an industrywide standard in wireless data communications."
