Newsky - Model DZZ4 -Automatic Weather Station

• Suitable for various operational applications

The DZZ4 Automatic Weather Station is commonly used in applications such as:

Conventional six-element observation: air temperature, relative humidity, air pressure, wind speed, wind direction, and rainfall.

Conventional seven-element observation: the six elements above plus ground temperature (including grass temperature, surface temperature, shallow ground temperature, and deep ground temperature).

Expandable to include evaporation, visibility, weighing precipitation, sunshine, radiation, snow depth, cloud height, weather phenomena, atmospheric electric field, lightning, and other elements or sensors.

• Scalable system

When expanding an existing automatic weather station with new measurement elements or additional sensors, no modifications are required to the existing sensor connections or wiring. The new sub‑collector/sensor can simply be added to the system, accompanied by a simple software upgrade or configuration.

• Professional Operational Software

    The operational software, developed based on B/S and C/S architectures, features a clean interface, rich content, and easy operation. A real‑time unified monitoring and management platform provides: equipment status monitoring (e.g., signal strength, remaining battery days, solar panel charging efficiency, sensor status), data transmission, data quality monitoring, threshold alarms, data analysis and statistics, online upgrade via 4G communication, and site environment monitoring with alerts/alarms.

• High system stability and reliability

    Our company has 60 years of professional experience in the development and service of ground‑based automated meteorological observation. We have established a complete reliability laboratory and reliability management system. All equipment undergoes professional reliability design, testing, and validation.
