Product Overview

The piezoelectric rainfall monitoring station consists of a data acquisition host and a solar charging system. It directly transmits information wirelessly through data terminals such as GPRS, which is then forwarded to the data processing center by wireless network providers. It enables automatic monitoring, storage, and transmission of precipitation data, achieving unattended operation with automatic reporting capabilities. Rainfall status can be viewed in real-time through the data center.

Technical Parameters

Measurement Parameters

Rainfall Measurement:

Rain Intensity Range: 0.3～10mm/min

Resolution: 0.01mm

Measurement Accuracy: ±4% (daily cumulative rainfall)

Refresh Interval: 5s

Cumulative Rainfall: Total rainfall since power-on

Current Rainfall: Data is retained after rain stops until the next rainfall, automatically resetting to zero.

Duration of Current Rainfall: Unit is 5s, e.g., a value of 12 indicates 60s of rainfall.

Rainfall in the Past 1 Minute: Smoothed recursive value for the past minute.

Rainfall in the Past 10 Minutes: Smoothed recursive value for the past 10 minutes.

Peak Minute Rainfall: The highest rainfall in any minute during the current event.

Product Features

1.Observation parameters can be optionally configured based on actual needs.

2.GPRS wireless data transmission eliminates the need for communication lines, offering long transmission distances.

3.The solar + lithium battery power supply method not only avoids resource waste and space occupation from power line installation but also ensures no power failure even after over ten consecutive rainy days.

4.Supported by three aluminum alloy brackets.

5.Flange base installation ensures stable operation of the entire device, reducing sway and vibration.

6.Integrated design adapts to various observation environments.

Application Areas

Widely used in meteorological, hydrological, and water conservancy comprehensive monitoring stations, traffic road monitoring, agriculture, forestry, wind power generation, etc., for remote measurement of precipitation, rainfall intensity, and start/end times of rainfall. Applied in hydrological automatic reporting systems and automatic field monitoring stations for purposes such as flood control, water supply scheduling, and reservoir water management.
