A parking space sensor is a device used to monitor the occupancy of parking lots in real-time. Parking space sensors are typically installed in parking lots or garages and can detect whether a parking space is empty or occupied. They help drivers find available parking spots more easily and assist parking management systems in optimizing space utilization. Parking space sensors can use various technologies such as ultrasonic sensors, infrared sensors, or cameras to detect the presence of vehicles. The data collected from these sensors can be used for parking guidance systems, mobile apps, and analytics to improve overall parking efficiency and reduce congestion.
