Published on

Internet of things is the new technological concept that promises a new world where every physical object can be interactive, communicating with each other and controlled all over the Internet, with the potential to impact how we live and also how we work. The main task of this project is to investigate a low power wireless solution and implement an intelligent climate system that fits best to the IoT concept by applying new technologies. To facilitate this process, a wireless sensor network is designed and implemented for precision climate monitoring which provides to the user useful data about the general condition of their building in a user friendly accessible manner. The system aims to make the heating control and management more efficient as the user would be able to take informed decisions and thus to save energy and reduce the costs.

  4. 4. INTRODUCTION • What is the purpose of the IoT Climate system? The purpose of the project is to utilize IoT application technology for monitoring the climate parameters of the buildings. The system utilizes wireless sensor nodes that gather and transmit the data relating to the climate in different rooms of the building. The aim is to provide the user with the opportunity to monitoring the environment inside the building by having access any place – any time via Internet, in order to take an informed real time decision.

  6. 6. The research of the project is based on the inductive paradigm. This type of methodology can be described as a flexible approach that allows to researcher to examine real life examples and facts in order to reach a provisional interpretation. The aim is to examine previously implemented systems in order to find the most fitted technologies that can be exploited and applied in order to create a suitable system. -Literature review study and background research -Design of a prototype -Implementation of the prototype -Experimentation and evaluation of results METHODOLOGY 306AAE - Individual Project Realisation Author: Konstantinos Athanasiou

  15. 15. DESIGNING/SOFTWARE Software design The Arduino programming language is used for the source code of the system, which is an open source environment based on C/C++. The software design can be divided into three main parts: • Online Dashboard: The user interface communicates with the system via Internet and specifically with the MQTT communication protocol. The system displays the data according to an instruction that users have to send using the dashboard. • Gateway/Coordinator: The coordinator is the control centre of the system. It’s the unit that receives the requests from the web server and runs the execution process. This process involves multiple functions, which can be divided into two parts: Xbee- WSN interface and the Web server • End device: The End device waits for the request of the coordinator in order to execute a task depending on the instruction. There are two different tasks: sensor-data reading and switch pin state. Author: Konstantinos Athanasiou306AAE - Individual Project Realisation

  17. 17. DESIGNING/XBEE CONFIGURATIONS ZigBee configurations The ZigBee network can support three different types of devices: coordinator, router and end. The network of the proposed system is configured using XCTU platform with one coordinator and three end devices. •Coordinator (API mode) The network requires only one coordinator with the main function to initiate the network formation. Additionally, is responsible to handle the addresses of the nodes and manage multiple functions of the network, such as data sampling, security and sleep mode. •3xEnd device (AT mode) The end devices can transmit and receive information. The main advantage of such a device, is that they optimise low power operation using a number of different techniques. Also, end devices are capable to use as stand-alone operation in order to execute the task of data sampling, digital signal conditioning and analogue reading.
