Design of ocean intelligent sensor based on STM32

In order to realize a long time unattended data acquisition in a complex and harsh environment in the ocean, a low-power intelligent sensor based on STM32 chip is designed. The sensor system is mainly composed of the central control unit based on the ARM chip STM32F103R6, sensor probes, storage and power control unit. Through the detailed design of some key issues such as high-precision sampling, low-power processing, communication, an intelligent ocean sensor has been developed, which has many functions including self-test, self-calibration, self-storage and communication. The test shows that the intelligent sensor work with high stability, and can provide detailed data on deep-sea environment for research.
