In any country one of the daily tasks for the people are finding for the free parking slot. Searching for the parking slot people have been wasting a lot of their valuable time. By developing a system in which peoples are able to access the real time data about the presence of parking slot nearer to the user wherever they want is the main goal of this paper. Different sensors such as IR Sensor, RFID, NODE MCU etc. were used in this system. It can minimize the searching time, fuel consumption and reduce the pollution. Key Words: IOT, Smart Parking, RFID (Radio frequency identification system), Parking slot, NODEMCU, etc. 1. INTRODUCTION A huge problem is created day by day increasing vehicles leads to traffic. IoT is a broad area in which different sensors are being able to connect through the internet by some medium of data sharing protocols. The main goal of this parking system is easily to find, allocate the nearer parking and to find the available slots to park their vehicles. From paper [1] stated that in 2006 a survey has been revealed an estimation in France, due to 700 million Euros were lost 70 hours has been spent in searching for a parking slot. In some countries a lot of work have been done on parking management system. In 1997 Guangdong AKE parking technology corporation ltd. Was founded, it was the first parking technology, in China it was the first company to develop and introduce parking guidance system (PGS) [2]. In this paper, if we have to know that how many slots are vacant at particular parking slot different sensors are activated at parking slots to detecting the vehicles and sent this data to the server. There are few steps involved in the process:฀ To get the fastest route to the parking slot we have to check the availability of parking space. 1.1 Internet of Things The Internet of things (IoT) describes the community of physical objects things which are embedded with sensors, software, and different technology for the reason of connecting and replacing information with different gadgets and structures over the Internet Things have advanced because of the convergence of more than one technology, real-time analytics, system learning, commodity sensors, and embedded structures. Traditional fields of embedded structures, wi-fi sensor networks, manipulate structures, automation (such as domestic and constructing automation), and others all make a contribution to permitting the Internet of things. In the purchaser market, IoT era is maximum synonymous with merchandise bearing on the idea of the "clever domestic", such as gadgets and appliances (together with lights fixtures, thermostats, domestic protection structures and cameras, and different domestic appliances) that help one or extra not unusual place ecosystems, and may be managed thru gadgets related to that ecosystem, together with smartphones and clever speakers. IoT also can be utilized in the healthcare of structures. There are some of severe worries approximately risks withinside the boom of IoT, specially withinside the regions of privateness and security, and therefore enterprise and governmental movements to deal with those worries have started inclusive of the improvement of those which were worldwide standards. 1.2 RFID ฀In the parking slot we have to get access through RFID Card and Token. ฀ Vehicle user scan their bar Code and the payment is automatically deducted through RFID Card and Token for the user to get access at the time of exit. User can use the bar Code for vehicle identification.
