1. Product Overview of Piezoelectric Rainfall Monitoring Station

       Piezoelectric rainfall monitoring station, also known as piezoelectric rainfall monitoring station, piezoelectric rainfall monitoring station, piezoelectric rainfall monitoring station can measure precipitation, precipitation for meteorological observatories (stations), hydrological stations, agriculture and forestry, national defense, field reporting stations and other relevant departments. Parameters such as intensity and precipitation time provide raw data.

　　The WX-YJ2 piezoelectric rainfall monitoring station is a modern rainfall station based on the Internet of Things. It is composed of a piezoelectric rainfall sensor, a collector, a solar power supply system, a pole bracket, etc. The equipment can be sent in the form of wireless remote transmission. Rainfall data can be sent wirelessly and remotely to the monitoring platform.

　　Log in 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 histogram, hourly rainfall change curve within a day, and Bar chart. The cloud platform supports daily boundary time setting, daily rainfall alarm threshold setting, and data can be exported by EXCEL.

　　Piezoelectric rainfall monitoring stations can be widely used in meteorology, flood control, agriculture, hydrology and water conservancy, environmental protection, highways, airports and ports and other fields. It can not only provide original data for relevant departments such as meteorological observatories (stations), hydrological stations, agriculture and forestry, national defense, and field reporting stations to measure parameters such as precipitation amount, precipitation intensity, and precipitation time; it can also provide original data for flood control, water supply dispatching, power stations, and reservoir water regime management. Provide valuable real-time data.

　　2. Product features

　　1. The piezoelectric rain sensor uses PVDF piezoelectric film as a rain-sensing device, and uses an embedded AI neural network to distinguish raindrop signals to avoid false triggering caused by interference such as gravel, dust, vibration, etc. It has an integrated design and a beautiful appearance.

　　2. High measurement accuracy, wide range, good stability, low power consumption, and strong ability to resist external interference

　　3. It can work around the clock and is not affected by weather changes, and can monitor rainfall duration accurately to the second.

　　4. Maintenance-free, the raindrop contact surface is an arc-shaped design structure, and no rainwater is stored.

　　5. With automatic horizontal calibration function after installation, no on-site calibration is required
