Hence we need an automobile communication protocol like the CAN protocol for high-speed & 1000s of data transmission at a single time. The standard communication protocols like UART, SPI, and I2C are not reliable for this system. To enable the transmission and receiving of the data at a very high-speed standard automotive communication protocols are required.

Similarly, car manufacturers are constantly making their cars smarter by adding features like Autonomous driving, Airbag system, ABS (Anti-braking System), Telematics, Transmission Control, Battery management systems, Cruise control system, etc. In modern Vehicle systems, there are more than 60 to 100 sensor units for sensing and exchanging information. It is commonly found on modern machine tools and as an automotive diagnostic bus. We will transmit the DHT11 Sensor data over a certain distance using the CAN protocol.Ĭontroller Area Network also known as CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed, and high reliability. In this tutorial, we will learn about the CAN Bus protocol by Interfacing MCP2515 CAN Bus Module with Arduino.
