01Overview
Engineered for the field
A compact ultrasonic weather station that calculates wind speed, wind direction, air temperature, relative humidity, air pressure, noise, rainfall (or sunlight) and PM2.5 and PM10 (or CO2) in one housing. A built-in electronic compass means the unit only needs to be mounted level, with no orientation step, which makes it well suited to moving platforms such as ships and transport vehicles. The UV-resistant, waterproof and corrosion-resistant housing is rated IP54, power draw stays at 0.7 W, and data is shared over RS485 Modbus with cloud platforms, monitoring software or PLC screens.
02Key Features
What makes the WST-111 different
01
Mount without alignment
The built-in electronic compass means the station only needs to be level, with no north alignment.
02
Ready for moving platforms
Works on ships, transport vehicles and other mobile installations where heading changes.
03
Rugged compact housing
UV-resistant, waterproof and corrosion-resistant enclosure rated IP54.
04
Low power
Maximum consumption of 0.7 W suits solar-powered and battery-backed sites.
05
Open integration
Standard Modbus RTU over RS485 connects to cloud platforms, monitoring software or PLC screens, with secondary development supported.
