Can Bus: How It Works, Pros And Cons

The Controller Area Network (CAN) bus is a serial communication protocol developed by Bosch in the 1980s for automotive applications. It is a multi-master, multi-slave, half-duplex, and fault-tolerant protocol that is simple, low-cost, and reliable. CAN bus data can provide valuable insights into the performance and status of the connected devices, but collecting and processing CAN bus data can be challenging due to the high data rate, low bandwidth, and variable network conditions. MQTT and EMQX are open-source solutions that can help to overcome these challenges. CAN bus is now used in automotive, industrial automation, and marine electronics applications.
