Optical Rainfall Monitoring Station - Hydrological Encyclopedia

1、 Product Overview

YJ3 Optical Rainfall Monitoring Station is a modern rainfall station based on the Internet of Things, consisting of optical rainfall sensors, collectors, solar power supply systems, pole supports, etc. The equipment can send rainfall data wirelessly and remotely to the monitoring platform.

Login to the IoT platform to view real-time data and historical records. Rainfall data includes rainfall status, one minute rainfall, five minute rainfall, ten minute rainfall, one hour rainfall, daily rainfall, monthly daily rainfall bar chart, hourly rainfall change curve and bar chart within a day. The cloud platform supports setting daily boundary time and daily rainfall alarm threshold, and data can be exported to EXCEL.

Optical rainfall monitoring stations can be widely applied in fields such as meteorology, flood prevention, agriculture, hydrology and water conservancy, environmental protection, highways, airports, and ports. It can provide raw data for meteorological stations, hydrological stations, agriculture and forestry, national defense, field monitoring stations and other relevant departments to measure precipitation, precipitation intensity, precipitation time and other parameters; It can also provide valuable real-time data for flood control, water supply scheduling, power station, and reservoir water management.

2、 Product Features
