The WunderBar Internet of Things WiFi & Bluetooth Sensor Starter Kit is a quick start development tool for Software Application Developers unfamiliar with complex wireless hardware designing, and a complete open-source wireless hardware reference design that enables Hardware Design Engineers with a out-of-the-box development tool that helps users get started quickly building, inventing, developing, and experimenting with Internet of Things senor based designs using WiFi and BLE senor applications.
The WunderBar IoT Starter Kit from relayr mimics the appearance of a chocolate bar with a WiFi enabled master module, plus six detachable smart sensor mini-modules. Each module has Bluetooth Low Energy (BLE), a sensor or actuator, and an on-board battery. The mini-modules provide functionality including light, color, distance, noise, temperature and humidity sensing, plus an accelerometer, a gyroscope and infra-red (IR) remote control capability. The Starter Kit has available for download various software development kits (SDKs) for iOS, Android and Node.js. including test Apps which can be downloaded from relayr.io
Work right way
Each module is fitted with firmware that makes it fully functional from the start. Yet it's flexible enough to allow you to configure it for your App.
Fast and secure
Based on core technologies developed by Twitter, LinkedIn and Yahoo, the Wunderbar kit and Cloud constitute a fast, secure and scalable system.
Each sensor module runs on a single coin cell battery that will last for at least a month. It's because of the way the firmware utilizes the BLE transmitter.
