Problems solved by technology
[0002] With the detection and development of marine resources, sensors for marine hydrology and environmental monitoring are used more and more widely, but these sensors are mainly powered by traditional batteries, and there are problems such as regular replacement and charging difficulties.
Wave energy is an all-weather source of energy. Compared with common green energy solar energy, it is not affected by factors such as sunlight; for this reason, there are many types of power generation devices that use wave energy to drive propellers in the prior art. These use wave energy to generate electricity. The device cannot avoid gears and bearings and other components, although the power is large, it is easy to wear

Embodiment
[0016] Embodiment: The whole device of the present invention is composed of three modules of electric energy collection, storage and measurement, wherein the main body of the collection device module is two sea buoys, and the two are connected by two metal plates pasted together. When the float moves relative to the waves, the metal plate and the piezoelectric sheet encapsulated in it are deformed. The current generated by the deformation of the piezoelectric sheet flows into the storage module. The main function of the storage module is to rectify the current and store it in the capacitor and lithium battery, and then supply power to the measurement module (composed of low power consumption MSP430 single-chip microcomputer equipped with several sensors).
