SinoAR Low-Power Acoustic Release Module

The SinoAR Acoustic Release Module is a highly integrated, advanced device specifically designed for deep-sea data acquisition missions. This module enables precise remote control and release via acoustic signals, eliminating the need for cable connections and thereby simplifying the recovery process of deep-sea data acquisition equipment. The module consists of a communication transducer and a communication control board, offering high flexibility and compatibility. It can be integrated with various underwater platforms, such as Ocean Bottom Seismometers (OBS), marine surveying equipment, and buoys, and is widely used in complex marine operations including marine scientific research, resource exploration, and environmental monitoring.contactus
