Solar powered autonomous node for wireless acoustic sensor networks based on ARM Cortex M4

摘要

The project aims to show the hardware and software of a solar powered autonomous node for wireless acoustic sensor networks based on ARM Cortex M4. The device consists of the following components: a microcontroller, four microphones for audio processing, a radio frequency communication module, a microSD to store and read data, four buzzers to emit a sound, a GPS and a temperature sensor. Furthermore, the device can be powered by a battery or a solar panel. The device is characterized by low consumption and a small size.
