Aiming to meet the growing demand for greater precision in smart parking devices, Libelium, the Spanish manufacturer of hardware and IoT solutions, has integrated radar technology in detecting the availability of parking spaces.
The new Smart Parking node improves detection and stability performance thanks to a radar sensor which allows precise detection (99%) of vehicles parked over the device. When the device notices a change in the parking lot status, it sends the data to the cloud through the LoRaWAN network.
Radar technology offers improved performance compared to devices equipped with magnetic or infrared detection. Moreover, radar parking devices are not vulnerable to magnetic interference nor do they give false positives for vehicles parked near or in double rows. Their performance is more consistent in any condition of luminosity, more stable in case of long-stay parking and they are not affected by the proximity of traffic movements such as passing a bus or heavy trucks. Additionally, the maintenance of radar parking sensors is much easier as they are not affected by dirt, dust, rain or oil spills.
“Radar technology avoids the miscalibration problems that can be experienced with other types of technology. By using radar sensors instead of magnetic ones, the system can “see” objects on top when lots are occupied,” says David Gascón, co-founder and CTO of Libelium.
The nodes provisioning has been enormously improved, now delivered with default time settings and also unique LoRaWAN identifiers and keys. This allows the registration of all nodes in the LoRaWAN network server at any one time.
