Rainfall monitor Product Overview  Rain gauge, a precision instrument specifically designed to measure and record rainfall, can be used in meteorology, hydrology, agriculture, environmental protection and other, achieving accurate and real-time monitoring of rainfall.

YJ3 Optical Rainfall Monitor Station is a modern type of rainfall station based on the Internet of Things, which is composed of optical rainfall sensors, collectors, solar power supply systems, and vertical rod brackets. The equipment can send rainfall data in the form of wireless remote transmission, and can send data wirelessly to the monitoring platform.

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.

Optical rain gauge monitoring stations 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, hydrological stations, 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.  Rainfall monitor Product features

1. This optical rain gauge sensor uses a pure sine infrared light source, built-in narrowband filter, and the sensing surface reaches 78 square centimeters, which can measure rainfall with high precision and is not affected by strong sunlight and other light. The high light transmittance rain sensor does not affect the direct sunlight, and it can be compatible with other optical sensors built-in, such as light, total radiation, ultraviolet sensor, etc.

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 accurately monitor the duration of rainfall to the second.
