This paper, Supervisory Control and Data Acquisition (SCADA) for an Air-Conditioner using Visual Basic, illustrates the application of SCADA devices not only for industry but also for the home. As a SCADA master unit, the personal computer provides a graphical user interface (GUI) and automatically regulates the managed air conditioning system in response to sensor inputs. The AT89SC51 micro controller is applied for a Remote Telemetry Unit (RTU). This controller serves as a local collection point for gathering reports from temperature sensors and delivering commands to control relays for the actuators in both indoor and outdoor unit. The communications network, RS 232 protocol connects the SCADA master unit to the RTUs of the system. The engineering software tools, Visual Basic and Assembly language, are used to develop GUI and communication protocol between personal computer and micro controller.
