The Smart Parking v2 solution developed by Libelium allows citizens to detect available parking slots.

The node applies intelligent algorithms to detect changes in the state of the parking slot. Then data is transmitted with the LoRaWAN radio to the final server.

The nodes provisioning has been enormously improved. The nodes are delivered with default time settings and also unique LoRaWAN identifiers and keys. So it is easy to use the default settings to register all nodes in the LoRaWAN network server at a time.

The Smart Parking node improves the detection and stability performance thanks to a radar sensor which permits to certainly know when objects are placed over the device. The next table shows a comparative analysis of the current sensor technologies in the Smart Parking market:

The node provides OTA-S (Over-The-Air Setup). This allows the user to remotely configure the node parameters (sleep time, keep-alive, night-mode, etc) via the Remote Configuration Form. That makes it possible to directly install the nodes with factory default settings and then update them from the server side.
