The sonobuoy originated from military submarine detection¡Ait was also used to measure ocean acoustic signal by scientists¡Abut the continuous recording and transmitting design by early sonobuoy is not suitable for long-term or scheduled observations. In this research¡A¡§off the self¡¨ components were integrated to develop an autonomous sonobuoy¡Awhich can be used to measure shipping noise and marine life acoustic signal in coastal water. The electronic design is based on a PC motherboard¡Ait is currently configured with a maximum sampling rate of 44.1 kHz¡Aand a maximum storage capacity of 40 GB. The sound was collected by a plug and play hydrophone system¡Awhich is controlled by a program written by LabVIEW. In addition to the programmable data acquisition and low cost advantages¡Athe flexible design allows quick system expansion and adjustment¡Ait can also be configured to record from multiple transducers.
