In This Project, To Implement CAN Based Home Automation Two Nodes Are Constructed. The Node1 Is Interfaced With The Node 2. CAN Uses Only Short Messages, Which Means The Maximum Utility Of The Load Is 64 Bits. The Commands For Home Automation Are Given Through RF Transmitter, Keypad Setup. The RF Receiver Gets The Information For Controlling The Devices Connected With The Node1 And Node2from The PC Is Given To The Node2 Through Serial Port. From Node2 The Command Is Transferred To The Node1 Through CAN Cable. Similarly The Information From The Two Nodes Also Reported To The PC Through CAN Network. CAN Offers High-speed Communication Rate Up To 1M Bits/sec Thus Allows Real-time Control. In Addition, The Error Confinement And The Error Detection Feature Make It More Reliable In Noise Critical Environment. CAN Is A Two-wire, Half Duplex, High-speed Network System And Is Well Suited For High-speed Applications Using Short Messages. A CPU Is Needed To Manage The CAN Protocol. The PIC16F Microcontroller Is Used As The CPU.
