Review Paper on Low Cost Scada System for Micro Industry

The main objective of the project is to use the SCADA system to control data in real time. It is necessary to monitor all the processes and control the elements related to them because many processes are running simultaneously in large enterprises. We can achieve this goal by using technology such as Wireless SCADA (Supervisory Control and Data Analysis). The AT89S52 microcontroller is interfaced with temperature sensors. The microcontroller wirelessly transmits data continuously from the sensors, which are then received via a USB type trans-receiver connected to a PC or laptop. The computer software that records the data into a file and displays it on the front panel of the PC or laptop is loaded. On the SCADA screen, we can change the parameters such as the setting, the low limit, and the high limit. The microprocessor sends instructions to the appropriate relay as soon as the temperature sensor drops below a predetermined level. In response to their sensors, the field devices connected by the communicator are switched from ON to OFF. For the purpose of making the alarm sound on the PC when there is a malfunction, there are more restrictions and lower options. Thus SCADA can be used to control processes accurately and safely at hazardous locations. On the SCADA screen, we can change the parameters such as the setting, the low limit, and the high limit
