Raspberry Pi SCADA Zonal based System for Agricultural Plant Monitoring

SCADA (Supervisory Control and Data Acquisition) and DCS (Distributed Control System) are both famous terms in automation and they both have critical rules. There is rarely an industry in the world which are not auditing their outcome based on one of these terms. But IOT developed in recent years, mixing the functionality of these two terms has been going on too with various security challenges involved. Even some previous issues like the price of software and easy extendibility of them make the way for small industries to have their benefits. In this research paper along with the designing and comparison, two small SCADA systems for agricultural applications tries to reduce the size as well as address a zonal method to investigate the security problems. Till these days' researchers have shown lots of development to reduce the SCADA cost in different manner but, having the compact, powerful and small size host for SCADA system has not been reported before. One of the novel aspects in this design is hiring the Raspberry Pi as the smallest computer instead of PC or laptop which along with reducing the system cost can also reduce the whole design system. Besides, Web based SCADA system has been successfully designed here and used. This paper discusses the context of local as well as remote monitoring of an agricultural plant environment with the help of a Raspberry Pi network through which a SCADA System was established. This paper aims to prove that a far more efficient and cost-effective along a secure SCADA System for monitoring is possible with the lowest of efforts. So, having zonal idea will help system to achieve the aim of secure sensor monitoring without any kind of outside interference. The result shows the successful design and implementation of zonal idea as well as the perfect usage of Raspberry Pi as a small and reliable host.
