1. Product Overview

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 to the monitoring platform in a wireless remote manner.

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 to EXCEL.

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, agriculture and 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 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 ability to resist external interference.

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

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.
