Smart Parking System Mobile Application using Ultrasonic Detector

Finding an empty parking lot is a big challenge as it can take lots of time and resources. This paper describes the design development prototype smart system for assisting vehicle drivers who always experiencing problem in finding indoor lots. The objectives proposed are to develop IoT utilizing ultrasonic sensor detect presence mobile application display layout car locate lot.For controller unit, consists Arduino UNO microcontroller which programmed using JavaScript language. used control sensor, build connection with firebase server update any changes hardware firebase. enables transmitter collects sensing data be passed transmission acquisition unit. Once detects car, signal read processed by before sent status availability. accuracy detection 100% standard deviation A0 A1 0.5 0.32 respectively. result availability automatically updated phone real-time.
