Sensor to cloud developer kit accelerates IoT design

A prototyping vehicle designed to help engineers to connect wireless sensor nodes to mobile devices and the cloud has been introduced by Silicon Labs. The Thunderboard React developer kit features a battery powered, sensor rich demonstration board with Bluetooth low energy technology and an ARM Cortex-M4 processor for IoT connectivity, along with open source design files and software for mobile apps running on Android and iOS devices.

“Thunderboard React, along with our free firmware and source code, provides developers and makers with an easy way to evaluate and prototype wireless sensor nodes that connect to the cloud through Bluetooth low energy,” said Daniel Cooley, general manager of IoT products. “Our customers can now create more competitive, secure and useful IoT products that deliver cloud-based analytics and business intelligence for end users.”

Thunderboard React claims to simplify IoT design by providing the sensing, processing and wireless components needed to connect a battery powered sensor node to a cloud database. The on-board sensors measure motion, light and environmental conditions, and this real time sensor data is transmitted to the cloud over a Bluetooth connection. An intuitive mobile app displays the data on smartphones and tablets while enabling the user to control the board. No RF expertise is required to develop wireless sensing applications with Thunderboard React.

The energy efficient components on the Thunderboard React board enable developers to create IoT nodes powered by small coin cell batteries. The components can be integrated and modified to enable Bluetooth-to-cloud connectivity for a developer’s particular IoT application.

The Thunderboard React kit includes:
• BGM111 globally pre-certified Bluetooth low energy module
• Si7021 relative humidity and temperature sensor
• Si1133 UV index and ambient light sensor
• 6-axis gyro/accelerometer
• Hall effect position sensor
• Open-source design files
• Android and iOS mobile app
