A short demo using LTC3500 piezoelectric energy harvesting power supply and the energy friendly EFM32 Cortex-M3 microcontroller to create a wireless sensor node with LCD display, acquiring data from a 3-axis accelerometer and transmitting data over a ZigBee RF transceiver.
Energy harvested from the transducer is used by the accelerometer and radio according to the MCU´s optimized sequencing software. Status messages are displayed on the Starter Kit´s LCD, and the transmitted packet data is displayed on the computer software.
