1. Introduction

The Rainfall Monitoring Station is an intelligent monitoring device designed to measure precipitation. Constructed with a dual tipping bucket mechanism, it can measure minute rainfall, hourly rainfall, and daily rainfall. Users can configure thresholds, The alarm will be triggered when rainfall exceeds the configured threshold. The device uploads rainfall data and other parameters to the remote monitoring system, where the data is parsed and analyzed to determine the alarm status.

It utilizes 4G or NB-IoT communication technology and is solar-powered, featuring advantages such as easy installation, real-time monitoring , high detection accuracy, and stable operation.

2. Function

• Rainfall parameter collection

The device capable of measuring 1-minute rainfall, 1-hour rainfall, and 24-hour rainfall. Operating on a configured data collection and upload interval, Minimum collection interval: 20 seconds; minimum upload interval: 1 minute).

• Power supply parameter collection

The device collects power supply parameters, including charge/discharge voltage, charge/discharge current, and battery capacity.

• Data alarm reporting

The device is equipped with an alarm reporting function. The alarm will be activated if rainfall exceeding the preset threshold during a data collection interval, both rainfall data and device parameters are subsequently transmitted to the remote monitoring system.

• Remote configuration

The device enables remote parameter configuration and software upgrades, characterized by easy operation and maintenance.

3. Installation instructions

• The rainfall monitoring terminal requires monthly maintenance, maintenance frequency should be adjusted based on actual operational demands under special environmental conditions.
• If installing the device near high-power radar systems or wireless transmitters, conduct an on-site electromagnetic survey to assess potential electromagnetic interference (EMI). Mitigation measures must be implemented if EMI risks are identified.
• Install the device away from trees, utility poles, high-rise buildings, or other structures that may disrupt airflow or create turbulence, as these factors could compromise measurement accuracy.
• Choose an open installation area where the distance between the device and any obstruction exceeds 10 times the obstruction's height. This ensures unimpeded rainfall measurement and data reliability.
