Description

TECHNICAL FIELD

[0001] The present application relates to the field of hydrological monitoring technology, in particular to a hydrological monitoring sensor. BACKGROUND

[0002] Hydrological monitoring is an important basic work for mastering water resources dynamics, ensuring flood control safety and supporting ecological protection. In river, lake, reservoir and ocean environments, it is necessary to obtain key data such as water level, flow, water temperature and water quality in real time.

[0003] The hydrological monitoring sensor usually consists of a sensing module, a data processing module, a communication module, a power supply module and a protective shell. The sensing module contains various types of sensitive elements, such as pressure sensors for measuring water level, ultrasonic sensors for non-contact liquid level measurement, and electrode sensors for detecting water quality parameters. The data processing module amplifies, filters, digitizes and calculates the original signals collected by the sensing module, and converts them into standard data. The communication module supports wireless communication methods such as 4G / 5G, or wired communication methods such as optical fiber and RS485, to realize remote data transmission. The power supply module uses a combination of solar panels and lithium batteries to ensure long-term stable operation.
