SCADA is the abbreviation of “Supervisory Control and Data Acquisition.”SCADA system basically used in industry for process automation. Process automation is in the sense of data acquisition as well as controlling. Conventional SCADA system working with PC, and some older operating system based mobile phones as client. This paper representing an Android phone as supervisory controller and PC used as a base station to store the data as well as for further processing. The wireless communication between the mobile phone and the base station is performed by using Bluetooth application protocol. The test result have indicated that the mobile phone based SCADA integration using Bluetooth data transfer scheme could enhance the performance of Plant and Machinery in a day without causing an increase in the response time of SCADA function. The supervisor of the plant can see the status of parameter without visiting the site . Therefore this system reduces the maintenance cost and necessity of continuous monitoring. Therefore this system increases the productivity and performance of the Plant.
