WIRELESS ENVIRONMENTAL QUALITY MONITORING SYSTEM

Abstract

Advances in commercial compact integrated circuit technology have made it possible to integrate wireless transceivers, signal processing, and sensors in a single integrated circuit package. Such solutions provide a low-cost means of communication with the physical world and can have applications in areas as diverse as security, production management, research and environmental monitoring. We outline the challenges of system design for a distributed sensor network in which each node has a limited power source and communication channel. The nodes must establish a synchronous network with multiple hops, determine locations, and communicate for purposes such as relaying a signal and transmitting data to a server device. The confluence of low-cost wireless, computing, and sensors has created a new generation of smart devices. The use of tens and thousands of such devices in self-organizing networks has led to the creation of a new technology called wireless sensor networks. In this article, we will consider an example of the use of such a network based on the Bluetooth Low Energy (BLE) wireless data transfer protocol, which gave a serious impetus to the development of wireless sensors. Together with organic polymers, which are used as a sensor layer, it is possible to achieve high energy efficiency and selective sensitivity in monitoring. It is also worth noting the fast and cheap production of electronics based on organic polymers. Due to the semiconductor and flexible properties of organic semiconductor materials, flexible organic electronics has become the core of our technology. The field of organic electronics is entering a commercial phase. The appearance on the market of the first prototypes based on organic transistors made from solutions is intended to expand the existing presence in the market of organic electronic devices. We'll look at some of the key performance requirements for working devices. We will also look at some of the important advances in semiconductor design and device manufacturing technologies and discuss some of the technical challenges that are needed to optimize next generation products.
