Parking is a temporary stop for a car. The need for parking space is important in the center of activities. The rate of increase in the number of cars is not directly proportional to the availability of parking space, so the available parking space is currently not adequate with the number of vehicles using the parking lot. Moreover, parking land users can not know the available parking location information from a distance. This can cause queues, delays, or congestion and will disrupt the smoothness of traffic if the availability of parking space capacity in place is not able to accommodate vehicles to be parked. For this purpose, this research aims to design and build a prototype to inform the parking location available to prospective users of parking area using web and microcontroller based on ESP8266. This research begins by analyzing and doing system design both hardware and software, then proceed with coding programming. The last stage is a test of tools and systems to find out if the tool has been running properly as planned. The system is designed to be able to work automatically in checking the available parking location conditions and is not available as well as calculating the number of cars passing through the parking gate and informing potential users of the parking lot. The working system of this tool is by reading the microcontroller on the sensors that have been installed behind each parking location to find out the parking conditions and sensors found in the parking gate to find the car passing, then update the database so that it can provide location information parking to users through the website.
