SCADA controlled smart home using Raspberry Pi3

The main objective of this article is to develop a smart home system using SCADA, Raspberry Pi3 Module and Wemos-Dl board. Nowadays people are expecting to control the home appliances through remote control. This expectation is fulfilled by our advanced technology. In this paper, we are using SCADA, Transmission Control Protocol/Internet Protocol (TCP/IP) and Message Queuing Telemetry Transport (MQTT) to develop a smart home system. Modern homes are expected to have centralized control system, instead of conventional switches which are fitted on walls. If the user wants to control the appliances, he has to move near the wall and control the switches. This method is inconvenient for the elderly and disabled people. So their difficulty to operate the appliances can be supported by the proposed smart home system which has a remote module to control the appliances. Remote controlled smart home system fulfills the needs of the people. Remote control operation is achieved by a PC (Personal Computer) is supported by IGSS SCADA. In the PC with TCP/IP protocol acts as a transmitter, which sends commands to the Raspberry Pi3 module. Raspberry Pi3 receives the commands from SCADA. Raspberry Pi3 send the commands with addresses to a terminal units (Wemos-Dl board) by MQTT. Each terminal unit receives the address from the Raspberry Pi3, if the terminal unit address matches the Raspberry Pi3, it can control devices or measured parameter, then sends this parameter with its address to the Raspberry Pi3. The Raspberry Pi3 sends these data to owner's PC. In this article Wemos-D1 controller board which contains an ESP8266 IC is used. The loads are interfaced to the Wemos-D1 controller using electromagnetic relays.
