Bachelor Thesis Description
The goal of the thesis work was the construction of a wireless sensor network (WSN) with acoustic deforestation detection capability. To this end, the WSN node was designed such that it is capable of acquiring sound from an analog microphone, sampling the sound using a microcontroller ADC, transferring the samples to a computer through a wireless connection, and analysing the sound to determine whether the sound is of a chain-saw or other natural forest sound. A ST-Micro STM32 Nucleo-64 board was utilized for signal acquisition and wireless transmission. A custom printed circuit board was designed and fabricated for the analog components and microphone.
