A fast-growing IoT startup specializing in embedded wireless, Blues Wireless has announced the general availability of their new developer kit, Sparrow. Offering significant cost savings, Sparrow is an efficient and economical developer kit that addresses the last mile problem of connecting a group of low-cost, low-power sensors to the Internet for shared data backhaul to the cloud. The developer kit provides a complete system, with reference hardware, example firmware, and an easy-to-deploy web application.

Sparrow deployments consist of a Sparrow Gateway and one or more Sparrow sensors. The power-efficient Sparrow Gateway provides cellular or Wi-Fi backhaul and orchestrates LoRa-based communication with Sparrow Sensors.

Sensors are organized into clusters, and LoRa-based sensor data is routed through inexpensive Notecards that combine prepaid cellular connectivity, low-power design, and secure “off-the-internet” communications in one 30- x 35-mm System-on-Module (SoM). Notecards enable the Sparrow Gateway to use NB-IoT, Cat-1, Cat-M, or Wi-Fi for communication backhaul. The Notecard was designed to simplify cellular, democratizing a capability formerly only available to sophisticated engineering firms. The developer kit enables unprecedented speed from concept-to-deployment. Beyond simplifying cellular, the full range of Notecard offerings now simplifies wireless across cellular, Wi-Fi and LPWAN technologies.

“When building wireless IoT solutions, developers sometimes run into scenarios that require lower-cost connectivity than they can achieve with a cellular or Wi-Fi module in every device,” said Brandon Satrom, VP of Experience Engineering at Blues Wireless. “Sparrow provides low-cost LoRa-based sensors for these use cases and leverages the Notecard for cloud backhaul, to simplify and accelerate the process of building device cluster-based applications.”

This is particularly evident in several fixed-location device cluster scenarios, such as occupancy sensing or facilities management using smoke sensors. Sparrow offerings present an opportunity for dramatic per-sensor cost savings – with LoRa support as low as $1 per sensor.
The Sparrow developer kit is now available for purchase in the Blues Wireless online shop for prototype acceleration.
