Physical Web is a Google's Internet of Things (IoT) via simple
web-based API. Every
object broadcasts its URL periodically via Bluetooth 4.0 Low Energy (BLE). There is both an
Android and an iOS
app available for download (both of which are open source) that will
monitor for broadcast URL advertisement packets and present them to
the user. Hardware
hackers can evidently
build their own smart objects using the
RFduino, a diminutive
microcontroller that runs on battery power and is Arduino-compatible.
