Development of smart home automation system based on PLC

Using a Programmable Logic Controller (PLC), this paper proposes an implementation of a smart home system. The program of smart job scheduling is an energy-efficient home system. The machine is operated automatically, is energy-efficient, and creates a more relaxed and simpler environment for life. It also increases the safety of the house. In addition to this, the central control unit manages and controls several operations, including control of the main entrance and garage, control of electrical connections, and security control system using PLC and relays with a regulated schedule. The core software for PLC is built using a CX-Programmer. CX-Programmer is used to create a ladder diagram that capable of processing, sequencing, scheduling, and reading instructions. CX-Designer is used to provide Human Machine Interface (HMI). The activities can be performed exactly according to the schedule defined by user demand
