The issue of the driving safe has been more and more attended in the government and car industry. One of the major driving safe techniques is the vehicle diagnostic system development.
In Addition, SMART City is an important economic strategic planner for the economic transformation and upgrading of the country. Many countries have been at the forefront of technology Progress and start smart city development programs.
Due to the two main factors mentioned above, it has become necessary to connect cars to the cloud.
The aim of this project is to connect the car with gateway, which will open the way for a number of renovations towards a smart city.
The project consists of two sides end-Node and receiver, the communication between the two sides is done using LoRaWAN. The end-Node is connected to several sensors that collect data from the vehicle, RPM, speed, motion (if the car is moving), pressure and temperature, and transmit this information using LoRa device to the receive module.
Each side of the system consists of: microcontroller, ESP32, which controls the system, it sends requests, receives, responses and process the collected data and a transceiver, RFM96, that transmit/receive data.
The end node includes also two sensors: MPU6050 – motion sensor, BMP280 – pressure and temperature sensor. And ELM327, a programmed microcontroller for translating the on-board diagnostics (OBD) interface found in the cars.
