Abstract

The monitoring of environmental parameters in industrial areas where potential sources of pollution exist is very important from the point of view of prevention of environmental accidents. In this paper, we propose a solution for the monitoring of the environmental parameters with the local acquisition through specific environmental and movement sensors and data transmission to a higher hierarchical level through the use of MODBUS communications. A flexible hardware structure and software development concept are presented to offer local information and to be integrated into an environmental quality monitoring network.

Highlights

  • Environmental monitoring is a set of complex activities aimed at obtaining data on the environment's quality and their processing

  • The configuration of the monitoring system of the environmental parameters that he proposes in this paper involves the use of sensors produced by the company Tibbo Technology which is focused on designing, manufacturing, and marketing programmable IoT modules, boards, and controllers for the Internet of Things (IoT), Industrial Internet of Things (IIoT), and automation applications [6]

  • This paper presents its own contribution related to the Modbus communication protocol and its use in a network of sensors

Summary

The issue of environmental monitoring

Environmental monitoring is a set of complex activities aimed at obtaining data on the environment's quality and their processing. A very important aspect is related to the distance between the measurement points and the data processing location If these distances are large, different radio technologies are used for data transmissions, such as GSM and wireless standards as IEEE 802.15.4 or ZigBee protocols [5]. If these distances are of the order of tens or hundreds of meters, it is possible to use transmission technologies using various physical environments. This second variant has the advantage that it offers the possibility of remote powering of nodes and sensors
