Smart Car Parking System using Wireless Sensor Networks

Wireless sensor networking (WSN) technology has gained momentum in recent years. Due to the wide scope and multifaceted implementation of wireless sensor networks, they have been extensively used to create intelligent systems.In this paper, we have proposed a smart car parking system using wireless sensor networks. The system allocates parking slots to a user (driver) on the basis of availability along with efficiently utilizing the entire parking capacity. Our approach makes use of low-cost sensor nodes in each slot of the parking lot, which signals the availability of the slot. The status of availability is reflected on a mobile application called Blynk, so that the user can park the car efficiently. Users can save a lot of time by not having to search for parking lots that are free and can reduce the usage of fuel to a great extent. The system also utilizes ultrasonic sensors to ensure that the vehicle has been correctly parked with respect to the parking infrastructure. Furthermore, the system employs a gas sensor so that the leakage of flammable gases can be detected, which makes it safe for the users. By keeping the number of sensors low, cost is effectively managed without compromising on reliability. Thus, our smart car parking system project is an innovative method for effectively managing the process of parking.
