Surface temperature sensor

A specially developed surface and subsurface temperature sensor serves two purposes. In the summer months, it can provide information on the overheating of the pavement surface and the formation of a heat island, and in the winter months it serves as a valuable data input for a more sensorially complex icing prediction system, which is used for the automated management of the application of road salt.


  • surface temperature (supplemented by salinity sensor)

  • 60 mm below the surface (temperature under the concrete pavement pavement) a

  • 300 mm below the surface for frost detection purposes.



the battery-powered sensor has a lifespan of up to 10 years. Lifetime depends on broadcast frequency.



cylinder 120x60 mm


the sensor is installed by replacing the paving block and drilling the cavern to a depth of 300 mm using a standard drill. Subsequently, the surface around the detector is either covered with gravel or sealed with a concrete mixture.


the sensor is able to communicate via various IoT networks, i.e. LoRa, SIGFOX or IQRF. According to the limits of the given network, it provides information to the cloud environment.


the sensor is a temperature sensor supplemented with salinity detection.


the sensor is battery-powered and does not require connection to the mains.

How the installation works

Installation surface temperature sensor

Step 1.

The sensor is installed by replacing the paving block and drilling the cavern to a depth of 300 mm using a standard drill. Part of the excavated base gravel is set aside for final backfilling.

Step 2.

One of the temperature sensors is lowered into the 30 cm cavern, the other is inserted under the adjacent pavement, i.e. to a depth of 6 cm.

Step 3.

By gradual dusting, the sensor gradually settles in order to obtain the necessary stability on the soft bottom and at the same time avoid damage to the sensor's supply cables.

Step 4.

After settling and sprinkling with sand, the last approx. 3 cm is covered with small gravel, set aside for the final filling.

Step 5.

The sensor can be embedded with standard concrete mix instead of gravel and is walkable. There are also subsurface variants, placed, for example, in the body of the road.

Surface temperature sensor installation detail

Just scan the QR code

Each detector is registered with a unique QR code, which the installation crew reads using the registration mobile application at the installation site. This will automatically register the sensor element with its ID, GPS location and time of installation. In addition, the application itself offers to carry out the installation according to the prepared plan, as it provides the installation crew with navigation to the scene of the crime and continuous monitoring of the completion of the daily task.
