Ekahau Launches Wireless Environmental Sensors

February 16, 2011

The Wi-Fi-enabled temperature and humidity sensing tags automatically monitor areas where changes in the environment could be harmful, particularly in healthcare, retail, manufacturing, and hospitality applications.

RESTON, VA /PRNewswire/ -- Ekahau Inc., a worldwide leader in high-performance Wi-Fi-based real-time location systems (RTLS), introduced three new wireless temperature and humidity sensor tags that provide an automated way to measure, monitor, and manage areas where changes in the environment could be harmful. The tags are designed to assist with regulatory compliance and improve operations in a number of industries, including healthcare, retail, manufacturing and hospitality.

Because the Ekahau tags are wireless and battery powered, they are easily configured and can be deployed in various environments without having to run expensive cabling for power and connectivity. The tags have a battery life of up to three years when set at a 15-min. reporting interval, and are capable of sampling temperature and/or humidity every 15 sec or as required for the specific application. Onboard heuristics enable the tag to immediately report anomalies if they occur between reporting intervals.

"The flexibility of the Ekahau RTLS solution is further underscored by the applications made possible with our new temperature and humidity sensing tags," said Arttu Huhtiniemi, Vice President of Product Management at Ekahau. "Not only can our solutions enable the existing Wi-Fi network to do tracking of critical assets and people, we can further leverage an organization's network infrastructure to ensure that proper temperature and humidity ranges are maintained with our wireless sensors. By improving the ROI of the Wi-Fi network and eliminating costly cabling requirements of wired applications, Ekahau's temperature and humidity monitoring tags lower the cost of remote monitoring of environmentally sensitive areas."

Unlike competing solutions on the market, Ekahau's two new temperature sensor tags—the TS1 and TS2—have extended cable probes that can be installed inside the environment, where temperature is being measured, such as a freezer or refrigerator. The TS1 tag has a single probe, while the TS2 is a dual-probe tag. Depending on the probe used, the tags' temperature range is from –200°C to 150°C (–328°F to 302°F).

The HS1 humidity sensor tag includes onboard sensors that measure relative humidity, ranging up to 100%, and temperature ranges of (–40°C to 85°C (–40°F to 185°F).

The TS1, TS2 and HS1 tags all offer audible and visual alarm indicators on the tags themselves and allow for programmable alarm limits and local data logging. With continuous data logging, the measurement data will not be lost even in the event of a network outage. All the sensor tags also incorporate the ability for the sensors to receive acknowledgments from the Ekahau servers and a smart re-try capability in case of data transmission failures.

Ekahau will be displaying and demonstrating these new tags at Booth 3701 during the HIMSS11 Annual Conference & Exhibition, February 20–24, 2011, at the Orange County Convention Center in Orlando, FL.

The TS1, TS2 and HS1 tags are now available.
