Intelligent Portable Infrasound Array (IPIA)
The objective of this project was to create a portable infrasound array.The system had the following requirements:
✓ Firmware running at real-time✓ Read pressure sensor at 100hertz
✓ Wireless communication between two MCUs
✓ Capture system location using a GPS
✓ Time stamp capture data
✓ Solar tracker to find optimal postion for the battery charger
Overview
- Delivered custom embedded software in real-time (FreeRTOS) to meet latency constraints of 10 ms
- Established data acquisition of pressure sensor (DS-0091) at 80Hz with digital filter to avoid aliasing
- Built short-distance wireless communication via Bluetooth (HC-05) by sending packets through UART
- Integrated custom GPS (SIM33EAU) API by parsing serial data with NMEA protocol
- Learned documentation system (Doxygen) to generate proper software documentation
