What if you don’t have AC power at your preferred location?

Mini-RWIS Systems

Off-grid systems in a cost-effective package

Mini-RWIS solutions are the ideal solution for densifying existing road weather networks and creating new networks in locations without AC power. These solar-powered systems feature a range of standard non-invasive road and meteorological measurements optimized for off-grid usage.

Mini-RWIS delivers true off-grid RWIS stations deployable anywhere with cellular communications coverage. Data can be managed and visualized using Campbell Cloud data services or exported to 3rd party software systems using industry standard communication protocols.

Key features:

  • Multiple sensor options – feature rich, flexible, compact RWIS system
  • Lower installation costs – no AC power or additional roadside cabinets required
  • Solar powered – no longer restricted to locations with AC power
  • Robust and reliable - utilizes Campbell Scientific’s field proven core data acquisition technology











Are you looking to densify your existing RWIS network with low-cost smart infill sensors?

Smart Sensors (EU sites only)

Self-powered, non-invasive, semi-mobile, 24/7 data


Wintersense™ is a fully integrated non-invasive smart sensor that is an order of magnitude more cost effective to install and maintain compared to other measurement solutions. With integrated power and communications and no complex installation or road construction requirements, Wintersense is the ideal solution for densifying and expanding measurement networks. Data is collected and transmitted 24/7 which can be used by winter maintenance forecast providers to direct real time operations.

Key Features

  • Non-invasive sensor – delivers air temp, humidty and dew point measurements
  • Easy to install – just strap it to existing street furniture or simple road-side poles
  • Integrated sensor, power and comms – fully integrated smart sensor with no separate power or communications needed
  • Data automatically transmitted to secure cloud platform, where clients can visualize / export / manage data
  • Semi-mobile sensor means it is easy to redeploy around your network, for example in troublesome hotspots or thermal profiling over all weather conditions


Campbell Scientific has extensive experience providing transportation weather monitoring solutions for a range of applications such as:

  • Winter road conditions
  • Wind monitoring on bridges, highways and railways
  • Road flood monitoring systems
  • Visibility monitoring for sand and dust storms
  • Wildfires and burn scar monitoring
