SKU: 5436-15 Categories: ,


The Model 5436-15 Mobile Surface Sentinel – Serial provides accurate surface temperature and air temperature from a vehicle, in real-time. Serial data is made available from the included sensor cable. This allows connection to on-board vehicle controllers without the need for extra equipment. Robust materials are used, providing rapid temperature response rates to meet the demands of road weather management professionals.

The Mobile Surface Sentinel sensor is mounted to the front of the vehicle, pointed at the road surface, with the power and communication cable routed inside the vehicle. A weatherproof connector is provided near the sensor on the cable for easy wire routing and sensor maintenance. The sensor provides a user selectable RS-232 or RS-485 (streaming or polled) output for simple integration into new or existing Automated Vehicle Location (AVL) units.

The Mobile Surface Sentinel Model 5436-10 is available in a wireless configuration that communicates via Bluetooth to an in-cab LCD display.
