This project proposes a simulation model of intelligent parking system that has the ability to search for vacancies in the building or parking through mobile phones using voice command. The purpose of this project is to be convenient and quick in searching for parking spaces and to count the number of car entering park area each day. The developed system uses the NodeMCU ESP8266 microcontroller to detect the vacancy status and count the number of users of the parking lot using infrared and ultrasonic sensors. The collected data will be sent to Firebase database. For voice command system it is developed by using Dialogflow to create ChatBot and connect with the Google Assistant. Users can interact using voice to search the vacancy in parking area directly. From the experiment it is found that the developed parking lot system can display the vacancies correctly. When increasing the number of cars into the parking lot the system can display the status that has changed correctly. Moreover when inquiring for parking the system can find the nearest vacancy for user. In the future there are plans to develop additional equipment and implement the proposed system in real locations.

The objectives of this research are to analysis design and develop the Information System to support activities of Nang Loeng Community Bangkok. Also to install test and evaluate the system. To develop the System Development Life Cycle (SDLC) method is used. To develop and implement PHP script language and MySQL database management system are used. And the system is installed on the Internet Server. To evaluate the satisfaction the 2 groups are the samples the first is the group of 19 operation users and the second is the groups of 30 general users. Convenience sampling is used for sampling method. Gathered and analyzed the data by statistical processing program for Windows software. The result of research show that the satisfaction of the first group (19 operation users) about input screen a data entry is in a good level (x=4.00). About working process and reporting of the system is in a good level (x=4.15) the satisfaction of the group is a good level (x=4.08) The satisfaction of the group (43 general users) the results appear in the same level to the satisfaction of the first group in every case (x=4.21). So the research results can be concluded that all samples are highly satisfied with this information system. And this system can be installed in real working and suit the user requirement.
