The document discusses using Controller Area Network (CAN) protocol for industrial automation and safety. CAN protocol allows for efficient and real-time communication between controllers. The proposed system uses sensors like temperature, gas leakage and light intensity sensors connected to microcontrollers to monitor these parameters. If any parameter exceeds a threshold, corrective actions like activating motors or buzzers are taken. CAN protocol provides high-speed and reliable data transmission between nodes. This ensures safety in industry by enabling monitoring and control of critical parameters.
