The Wintersense SDI-12 is a remote road surface temperature sensor designed for use with your Road Weather Information Systems (RWIS). It is an easy-to-deploy, non-invasive, compact, and lightweight sensor that you can mount on existing roadside structures such as streetlight columns or RWIS towers. The Wintersense SDI-12 has a cabled connection for power and communications with an RWIS station or data logger for data storage and forwarding.
With accurate, real-time road surface temperature data, you can forecast your winter road treatments, preventing traffic accidents and potential loss of life.

The Wintersense SDI-12 is equipped with a thermopile sensor that detects the presence of thermal radiation emitted from the target surface. The sensor also has an integrated optical filter that cuts off the visible and near-infrared radiation flux so that you get optimum ambient and sunlight immunity. These features, combined with an eight-second signal-averaging algorithm, provide you with best-of-class data for these measurement parameters:
