A smart parking IoT solution utilizes LoRaWAN technology to enable efficient parking management and improve the parking experience. Sensor devices are deployed in parking spaces to detect occupancy status, transmitting the data wirelessly via LoRaWAN connectivity. The sensor data is collected and processed in Sonar 2.0, which provides real-time parking availability information. Users can access this information through mobile applications or signage, guiding them to available parking spaces and reducing the time spent searching for parking. The solution optimizes parking utilization, reduces congestion, and enhances the overall efficiency of parking operations.
