Multi-cylinder wetland evapotranspiration separation monitoring device

The invention relates to a multi-cylinder wetland evapotranspiration separation monitoring device and belongs to the field of plant physiology, ecological monitoring and wetland meteorological hydrological measuring devices. The device comprises evapotranspiration measuring cylinders, a sensor data collecting unit, a central control unit, a remote transmitting unit, a water level adjusting unit and a solar power management unit. Pressure sensors fixed into water in the cylinders through triangular brackets are used for performing underwater in-situ monitoring, and separated combined monitoringis achieved according to a compensation relationship between the measuring cylinders. Through cooperation between the central control unit and other units, automatic timing acquisition, processing, storage and wireless transmission of evapotranspiration data can be achieved, and setting of initial values of water levels of the measuring cylinders can be automatically achieved at regular time. Through interaction with a r
