Cloud based radio frequency identification (RFID) car security system with NodeMCU / Wan Ahmad Faris Mohd Azmi

A car theft today is a common thing that is happening every day. This car theft is occurring because of the car driver’s carelessness and already comfortable with the existing car security system. Almost every day, we can see news about car theft in mass and social media. Car theft incidence usually happened in a place whereby car theft focuses on the car that vulnerable towards car theft. Hence, the vehicle like car have a high risk of being stolen from this incidence. When buying a car, the car owner may feel that there is a need to add with an extra layer of security. There are many available car security devices available on the market, like steering wheel lock and kill switch. These car security devices are excellent, but we are now in the technology age where a device can be smart enough by implementing the Internet of Things (IoT). Therefore, using an Internet of Things (IoT) technology, the car owner can get benefits by connecting the car to the cloud and have only authorized person entering the vehicle. The project implementation works out by using a magnetic door sensor, Radio Frequency Identification (RFID) reader, buzzer alarm, and relay module. The magnetic door sensor is to detect the state of the car door while the buzzer alarm function is to trigger the alarm when the car thief or car owner opens the driver’s car door. Then, the RFID reader is used to confirm the identity of the car thief or car owner. After that, the relay module function is to turn on the buzzer alarm and enable or disable the car ignition key switch. Hence, the system flows starting from the car thief or the car owner opening the car door, which triggers the buzzer alarm. Therefore, confirming the identity of the person require that person to scan the preregistered RFID card and tag on the primary and secondary RFID reader. When the RFID not examined, the ignition key switch will remain disabled, and the alarm will be turned on for about 10 minutes. On the other side, when the RFID scanned, the ignition key switch turns on, and buzzer alarm turns off. After both primary and secondary RFID reader scanned, the data from the magnetic door sensor and RFID reader send to the ESP8266 NodeMCU microcontroller. The AWS DynamoDB is responsible for storing the data and dispatch it from the ESP8266 NodeMCU. Meanwhile, the AWS SNS sends the data to the car owner using email and message.
