Rainfall Monitoring and Reporting System: Leveraging IoT for Automated Field Rainfall Monitoring and Wireless Data Transmission

Equipped with stainless-steel rainfall sensors and data acquisition units, this rainfall monitoring and reporting system is powered by solar energy, making it ideal for field deployment. It transmits rainfall data wirelessly to a monitoring platform and supports data export for hydrological and flood-control analysis.

Built on Internet of Things (IoT) technology, this system comprises a stainless-steel rainfall sensor, a data collector, a solar power supply, and a mounting mast, designed for long-term rainfall monitoring in outdoor environments. The system transmits monitoring data wirelessly; by logging into the IoT platform, administrators can view real-time rainfall status, precipitation amounts for specific intervals, as well as daily, weekly, monthly, and annual rainfall totals. Data stored on the platform can be exported as Excel spreadsheets, facilitating further statistical analysis and reporting by staff.

The system features robust technical specifications: a 200 mm collection aperture, a rainfall intensity measurement range of 0–4 mm/min, an accuracy of ±0.2 mm, and a resolution of 0.2 mm. It is powered by a 50W solar panel paired with a 20Ah battery and includes a 1.5-meter mounting mast, ensuring stable, continuous operation in remote areas without access to the power grid. The equipment is suitable for use in sectors such as meteorology, flood control, agriculture, hydrology and water conservancy, environmental protection, highways, airports, and ports. It provides meteorological stations, hydrological stations, and field monitoring sites with raw data, including precipitation volume, intensity, and duration.

In applications such as flood-control dispatch, water supply management, and the daily operation and maintenance of power plants and reservoirs, the real-time rainfall data provided by this system serves as a valuable reference—effectively overcoming the limitations of traditional manual inspections, which are often infrequent and result in delayed reporting. The equipment is easy to deploy and requires minimal maintenance. It enables long-term, continuous collection of rainfall data, providing a reliable and consistent information base for hydrological management and disaster early warning. This supports relevant authorities in coordinating operations based on changing rainfall conditions and enhances the level of automation in rainfall monitoring and management.
