Automatic rain gauge is a comprehensive observation instrument that can be used to measure and record various rainfall information. It plays a vital role in meteorology, water conserv, hydrology, agriculture, environmental protection and other fields.

1. Automatic rain gauge station Product Overview

YJ2 Piezoelectric Rainfall Monitor Station is a modern type of rainfall station based on the Internet of Things, which is composed of piezoelectric rainfall sensor, collector, solar power supply system, vertical pole bracket, etc. The equipment can send rainfall data in the form of wireless remote transmission, and can send data to the monitoring platform in a wireless remote way.

Login to the Internet of Things 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 bar chart, one-day rainfall change curve and bar chart. The cloud platform supports the setting of daily boundaries, the setting of rainfall alarm thresholds, and data can be exported in EXCEL.

The piezoelectric rain gauge station can be widely used in meteorology, flood prevention, agriculture, hydrological and water conservancy, environmental protection, expressways, airports, ports and other fields. It can provide raw data for relevant departments such as meteorological stations (stations), hydrological stations, agriculture and forestry, national defense, and field monitoring stations to measure rainfall, precipitation intensity, precipitation time and other parameters; It can also provide real-time data with reference value for flood prevention, water supply dispatch, power stations, reservoir water situation management and other fields.

2. Product features

1. The piezoelectric rain gauge sensor uses PVDF piezoelectric film as the rain sensing device, and uses an embedded AI neural network to distinguish rain droplet signals, avoiding false triggering caused by sand, dust, vibration and other interference， integrated design with exquisite appearance

2. High measurement accuracy, wide range, good stability, low power consumption, strong anti-interference ability.

3. Can work 24 hours a day, rain or shine, and the monitoring of rainfall duration to the second is precise.
