Surface Sentinel

Surface Temperature Sensor

The Surface Sentinel non-intrusive surface temperature sensor provides surface temperature, air temperature, relative humidity and dew point measurements for warning systems and fixed weather stations. Premium materials are used to meet the demands of road weather professionals.

The surface temperature is measured by an accurate non-contact infrared temperature sensor. Air temperature and relative humidity are measured from an accurate sensor from which dew point is calculated. The sensor has an integrated fan for applications where higher accuracy air temperature and relative humidity readings are needed.

HSE Surface Sentinel
Bridge May be Icy Flashing Warning Sign

Activate Warning Signs

High Sierra Electronics employs its road weather sensor technologies to activate ITS systems along the roadway to alert drivers of potential hazards:

  • Trigger flashing beacon signs directly from sensor wire
  • No controller reduces cost
  • Remotely turn on flashing beacon signs:“BRIDGE MAY BE ICY” | “CURVE MAY BE ICY” | “ROAD MAY BE ICY”
  • Low power sensor can be used in remote locations with solar power
