Wintersense uses smart-sensor technology coupled with IoT communications and a cloud-hosted data solution to enable rapid densification of road-weather networks. The Wintersense smart sensor is a completely integrated smart sensor, available in two forms.
Wintersense provides consistent data 24/7, which can be easily ingested by forecast agencies to improve route-based forecasting services. Road authorities can minimize expenses through smarter route-based treatment decisions with the additional confidence that Wintersense data provides.
Data from Wintersense smart sensors is delivered wirelessly via IoT networks to a cloud-hosted web application. Via the web application, users can create and manage networks of sensors; set quality-control rules and automatic alerts on incoming data; and export data via FTP, API, or Datex II polling.Read More
Wintersense smart sensors use infrared thermopile technology to measure road-surface temperature non-invasively. R2 sensors provide additional air temperature, humidity, and dew point measurements using an advanced digital sensor. A stainless-steel mesh filter on the integrated temperature and humidity sensor minimizes the effects of dust and dirt on the sensor, allows air exchange around the sensor element, and reduces the likelihood that condensation remains inside the filter cap. A small PTFE membrane filter is bonded to the surface of the element, which prevents any finer dust or mold from directly influencing the measurement.
Wintersense smart sensors are self powered via a user-replaceable 3.6 V 19 Ah non-rechargeable lithium thionyl chloride D-cell battery. Integrated communications within the smart sensor allow complete end-to-end data delivery to the cloud-hosted Wintersense web application.
