This sensor is a device for parked vehicle detection. It consists of a magneto-resistive sensor, a MCU for the management of data, a high-capacity battery, a NB-IoT radio module and a Bluetooth Low Energy Module (BLE) for short-range communications to App 4Park and for the maintenance on-field operations.


It is installed underneath the pavement to prevent vandalism and risk for pedestrians and cyclists. It can be sealed with cold or hot asphalt, resins, porphyry or stone tiles, so it can be virtually invisible when installed.
