Piezoelectric instrument used to measure rainfall Enables High-Precision, All-Weather Rainfall Monitoring

Leveraging PVDF piezoelectric film and an embedded AI neural network to identify raindrop signals, this instrument used to measure rainfall filters out various environmental interferences to achieve high-precision (millimeter-level), all-weather rainfall monitoring. Suitable for outdoor applications across multiple industries, it features a maintenance-free design, low power consumption, and ease of installation.

The instrument used to measure rainfall is a core rainfall data acquisition device for sectors such as meteorology, hydrology, water conservancy, transportation, agriculture, and forestry. Unlike traditional mechanical rainfall monitors, this device utilizes PVDF piezoelectric film as its primary sensing element combined with embedded AI neural network signal recognition. This fundamentally resolves industry-wide issues—such as false triggers caused by grit, dust, or mechanical vibration—thereby significantly enhancing the accuracy and stability of the monitoring data.

Featuring an integrated, unified structure with no moving mechanical parts or exposed components, the instrument used to measure rainfall effectively filters out interference signals from environmental debris like leaves, dust, and insects, preventing the recording of invalid data. Its curved contact surface prevents rainwater accumulation, eliminating the need for manual cleaning or maintenance during long-term outdoor operation and drastically reducing O&M costs. Additionally, the device includes an automatic leveling function; it self-calibrates parameters after installation, removing the need for manual on-site adjustments and simplifying the installation process. Compact and highly portable, the unit allows for rapid installation and removal, making it suitable for diverse field deployment scenarios.

The instrument used to measure rainfall boasts excellent hardware performance and environmental adaptability. It offers a measurement range of 0–4 mm/min, accuracy of ±4% or better, a resolution of 0.01 mm, and a sampling frequency of less than one second, enabling precise, second-level monitoring of rainfall duration and millimeter-level data acquisition. Powered by DC 12V with a power consumption of only 0.12W, its low-power design supports long-term, unattended operation. It operates within a temperature range of -40°C to 85°C and a humidity range of 0–100% RH, ensuring stable, all-weather performance unaffected by extreme weather conditions.

Equipped with a standard RS485 communication interface and the Modbus protocol, the instrument used to measure rainfall ensures stable, standardized data transmission and integrates seamlessly with various automated hydrological monitoring systems and field monitoring stations. The data it collects—including precipitation volume, intensity, and start/stop times—provides precise information to support flood control, water supply scheduling, and reservoir water management. It is widely applicable across diverse sectors such as meteorological monitoring, water conservancy and hydrology, road transportation, agriculture and forestry, and wind power generation.
