Gaz bazlı araçlar için akıllı hırsızlığa karşı güvenlik ve güvenlik sistemi tasarımı ve uygulaması

In the past few years, many cases of car theft operations have been recorded to utilised it in suspicious operations. In addition to some countries 'lack of oil, these countries tended to modify cars to run on liquid propane gas. Consequently, we have many problems related to protecting cars from theft and others to protect gas-based cars, such as temperature rising or gas leaks, which subsequently cause dangerous accidents. In this work, intelligent system is proposed to protect the cars from the theft and the accidents related to gas-based cars. The proposed system comprises of three major portions; the first one is the car security subsystem, the following part is the real time car tracking subsystem, and the last part is the car safety subsystem. The car security subsystem is based on the Arduino Microcontroller, Bluetooth module, vibration sensor, keypad, solenoid lock, and GSM module. When the car owner would operate his own car a special password should be entered from the keypad and another password from a special Android app, once the two passwords right the car will be operated normally. If one of the entered passwords is error more than three times or the car operated suddenly without entering the passwords the alarming system will be turned ON, the doors will be closed by the solenoid lock, and a warning message will be sent to the car owner via the Bluetooth module. The car tracking subsystem is based on the internet of things () technology with a programmed android app utilising the NodeMCU microcontroller and global positioning system. Finally, the car safety system is based on the Arduino UNO microcontroller board, MQ-2 gas sensor to reveal the gas leak, flame sensor to reveal the appearance of the fire, the temperature sensor to monitor the ambient temperature of a vehicle's gas container, and Bluetooth module. In addition, the user will be able to monitor all the status of the safety (i.e. temperature, gas leak, and flame detection) via the compatible android app
