Acoustic Detection Array (ADA) aims to detect and locate the source of large sonic impulses often indicative of poaching in the wild, blast fishing, and other loud sounds. This is done by deploying self-sufficient, low-cost battery-powered nodes with appropriate sensor equipment, that seamlessly connect over RF for data transmission. The use of multiple nodes allows the accurate and precise location detection of the origin of a high impulse acoustic sound. This project involves the design and construction of a complete array of nodes utilizing various hardware parts, a unique PCB, and various software signal processing algorithms.
