Solar Dice: a Sensor Node in the Internet of Things (IoT) Reference Design

Description

The Solar Dice are a battery-less: wirelessly-transmitting device for the Internet of Things.  An onboard accelerometer detects the orientation of the Dice and wirelessly transmits this to a host: such as a USB dongle or smartphone.  The reference design demonstrates an ultra-low power sensor node: which is enabled by ultra-low power optimized code for the CC430 and ultra-low power management through the TPS62740.  The entire system draws a mere 2.36µA when in standby mode.  The Solar Dice are just an example of an unlimited number of different sensor types (temperature: humidity: pressure: etc.) that are enabled by the TPS62740 and CC430.
