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.
THE SENSOR CONSISTS OF THREE TEMPERATURE SENSORS
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.
Specifications
LIFETIME
the battery-powered sensor has a lifespan of up to 10 years. Lifetime depends on broadcast frequency.
DIMENSIONS
cylinder 120x60 mm
INSTALLATION
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.
COMMUNICATION
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.
DETECTION
the sensor is a temperature sensor supplemented with salinity detection.
POWER SUPPLY
the sensor is battery-powered and does not require connection to the mains.
How the installation works
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.

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.
Mobile application or just scan the QR code
There is a mobile application in which you can get information about individual sensors by simply scanning a QR code.
You can find everything in one place
All data is available online in a clear environment. Thanks to this, it is possible to work with data effectively and use it in practice.
