RT Journal Article SR Electronic A1 Palanisamy, Aravindh T1 Home Automation Using PLC and Arduino JF Acta Mechanica Slovaca YR 2020 VO 24 IS 1 SP 56 OP 68 UL https://www.actamechanica.sk/artkey/ams-202001-0008.php AB In this work a PLC has been used for controlling the home appliances. For that we are using several types of sensor and actuators and some logical operations for controlling the systems. As PLC is a controller which will help us to control and compute the logical operations based on our program. Along with this, also Arduino UNO have been used for this purpose. Tia portal and Arduino software are used for programming. And in addition, a HMI has been used for controlling and monitoring the system and for security purpose. The reason behind using the PLC is that it is durable, flexible, communication and minimum maintenanc
