HFY-WS400 All-in-One Ultrasonic Weather Station
HFY-WS400
The HFY-WS400 packs a full meteorological payload into a single maintenance-free unit. Ultrasonic wind sensing means no cups to jam and no bearings to wear out — the #1 failure point of mechanical stations in dusty or freezing environments.
Key Features
- Ultrasonic wind speed & direction — no moving parts, instant response
- Integrated T, RH and barometric pressure sensors
- RS485 with Modbus-RTU and ASCII protocols; optional SDI-12
- Optional rainfall, solar radiation and PM sensors stackable
- IP66 housing, UV-resistant ASA, operates from −40 to +70 °C
- Low power (< 25 mA) — runs for weeks on battery, forever on solar
Applications
Agriculture micro-climate networks, road weather information systems (RWIS), construction & mining dust compliance, solar farm resource assessment, smart-city environmental grids.
