Mobile Surface Sentinel

Vehicle Mounted Surface and Air Temperature Sensor

The Mobile Surface Sentinel—part of our mobile devices family—is a precision instrument that provides surface temperature and air temperature, in real-time, from a moving vehicle to an in-cab display unit. It detects and audibly and visually alerts the vehicle operator of possible freezing conditions. Features:

  • Industry leading rapid response time to changing air and surface temperatures
  • Simple installation with multiple mounting options. Typically mounted on the front bumper or mirror of the vehicle
  • High accuracy infrared temperature and air temperature sensors
  • Fully encapsulated sensor design is rugged and weatherproof
  • Power is the only connection required. Low power standby mode allows connection directly to vehicle battery

The Mobile Surface Sentinel can be integrated in Automated Vehicle Locator (AVL) solutions for real-time weather data and fleet management.  Ask about our full Road Weather Information System (RWIS) packages.

Wireless Bluetooth Connectivity
Connection from the sensor to the Mobile Display Unit is through wireless Bluetooth. Simply connect the sensor to the vehicle battery and the display to the in-cab switched power source. No need to route wires from outside to inside the vehicle.

  • Color LCD display of surface temperature and air temperature can be seen in direct sunlight
  • Trending graph with auto ranging temperature scale enables you to make more informed decisions
  • Alarm output with user-defineable temperature threshold (low or high)
  • User-selectable temperature modes in Fahrenheit or Celsius
  • Displays alerts to vehicle operator of freezing conditions
  • Automatic or fixed brightness adjustment
  • RS-232 and RS-485 output directly from MDU

The MDU can be used as a wireless bridge when an in-cab display is not needed.
