Optical rainfall monitoring stations, also known as rainfall measuring instruments, use optical principles to sense rainfall and have extremely high measurement accuracy, accurate to the millimeter level. They can transmit real-time monitoring rainfall data to meteorological monitoring centers or related user terminal devices

1. Product Overview

YJ3 Optical Rainfall Monitor Station is a modern type of rainfall station based on the Internet of Things, consisting of an optical rainfall sensor, a collector, a solar power supply system, a vertical pole bracket, etc. 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 format.

The optical rain gauge can be widely used in meteorology, flood control, agriculture, hydrological and water conservancy, environmental protection, expressways, airports, ports and other fields. It can provide raw data for the measurement of rainfall, precipitation intensity, precipitation time and other parameters by relevant departments such as meteorological stations, hydrological stations, forestry, national defense, and field monitoring stations; it can also provide real-time data with reference value for flood control, water supply dispatch, power stations, reservoir water situation management, etc.

Second, 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 accurately measure rainfall without being affected by high-intensity sunlight and other light. The high-transparency sensing cover does not affect direct sunlight and 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 ability to resist external interference.

3. Can work 24 hours a day, not affected by weather changes, and precise to the second rainfall duration monitoring

4. Maintenance-free, raindrops touch the surface of the arc-shaped design structure, which does not store rainwater.

5. Retrofitted with automatic level adjustment function, no on-site adjustment required.

6.Low power collector: static power consumption less than 1mA
