Compact Smart Automatic Ultrasonic Weather Stations for Wind Illumination Pm2.5 Noise Rainfall

Top optical rain gauge, middle ultrasonic anemometer, and bottom solar radiation shield are integrated into one compact unit, covering up to 8 meteorological parameters in a single device.

Delivering tighter error control at low speeds and proportionally accurate readings at high wind speeds up to 60m/s.

Barometric pressure measured across 0 to 120kPa with plus or minus 0.15kPa accuracy and a long-term drift of only -0.1kPa per year, suitable for aviation, navigation, and altitude-sensitive deployment

Built-in noise sensor covers the full range from quiet ambient environments to near-industrial sound levels, with plus or minus 0.5dB accuracy and less than 3dB per year long-term stability.

High-precision 3-axis compass eliminates the need for north-aligned installation, enabling accurate true wind direction measurement on ships, vehicles, and any mobile or fixed platform.

Top-mounted optical rain gauge with 6cm sensing diameter and 0.1mm resolution handles extreme rainfall bursts up to 24mm per minute without overflow or missed counts.

Measures solar irradiance across 0 to 1800 W/m2 with less than plus or minus 3% accuracy at 150 W/m2, supporting photovoltaic site assessment and agricultural light monitoring applications.

Environmentally friendly ABS polymer shell withstands UV exposure and operates reliably across a -20 to plus 80 degrees C range, meeting IP65 waterproof and dustproof protection requirements.

Draws only 1.2W maximum across a 10 to 30VDC input range, enabling solar panel or battery-powered operation in remote grasslands, alpine stations, and off-grid marine deployments.

Users choose either PM2.5/PM10 particle monitoring at 0 to 1000ug/m3 or CO2 at 0 to 5000ppm as an add-on module, keeping the base unit flexible for air quality or greenhouse gas monitoring needs.
