WS J-Series Smart Weather Sensors - Powered by Lufft expertise 

Trusted environmental intelligence for confident weather-dependent decisions

Reliable weather intelligence for solar, meteorological and road weather applications.

The decisions you make are only as good as the data behind them

Weather influences critical decisions every day.

From optimising solar performance and improving forecast accuracy to supporting safer road weather operations, organisations rely on environmental observations they can trust.

When observations become unreliable or unavailable, performance, safety and operational efficiency can all be affected.

Reliable environmental intelligence isn't just about collecting data. It's about making decisions with confidence.

Why Choose the WS J-Series?

Protect long-term data quality

Reliable decisions start with reliable observations. Enhanced diagnostics, heater voltage monitoring, and no-moving-parts sensing technologies help maintain measurement stability, identify issues earlier, and support confidence in long-term observations and weather records.

Simplify deployment and maintenance

Standardise with one platform across your network. Common communications protocols, read/write SDI-12 support and a shared platform architecture help streamline installation, integration and ongoing maintenance.

Meet evolving industry requirements

Full IEC 61724-1:2021 compliance, WMO-compliant wind gust capability and WMO present weather reporting help support trusted, standards-compliant observations.

 

Reduce unnecessary maintenance

Spend less time troubleshooting and more time acting on data. Built-in diagnostics, active heating monitoring and automatic over-voltage protection help support dependable operation while reducing unnecessary maintenance visits
