Development of a Bluetooth Sensor Gateway for Smart Building and IoT

Esensors is developing an Internet via Ethernet gateway for Bluetooth LE enabled sensors suitable for smart buildings, smart grid and Internet of Things. The gateway is based on a standard Linux platform with a Bluetooth wireless transceiver which processes and reformats sensor data as Internet/Ethernet accessible formats.

The gateway is based on a standard Linux platform with a Bluetooth wireless transceiver which processes and reformats sensor data as Internet/Ethernet accessible formats. The intention is to provide APIs which will translate data from commercially available Bluetooth sensors into standard Internet formats. Esensors will rely on its experience in designing Websensors and other IP enabled sensors, as well as its experience in standards development, to provide a quick solution.

Bluetooth LE has become a preferred choice for many wireless sensor applications because of its attractive features, including automatic configuration (plug&play), good range, low power consumption and low cost. However most Bluetooth enabled sensors can only be readily accessed by cell phones or tablets, which are appropriate for personal sensors such as heart rate monitors, but not for those intended for smart buildings. For these applications continuous access to the Internet is needed, as provided by a gateway. Presently available Bluetooth gateways or access points are not LE enabled, do not provide sensor interfaces and have prices several times that of our proposed solution.
