A node is an intersection point that can generate, receive, store or transmit data along distributed network routes and allows us to analyze the data at a particular point. In a network node, each sensor has several parts such as transceiver with an internal or connection to an external antenna, micro controller, electronic circuits for interfacing sensors and energy source. The scaling of single...
The critical requirements for devices connected in Internet of Things (IoT) are long battery life, long coverage range, and low deployment cost. In our previous work, we developed cognitive controller for controlling the HVAC of non-domestic building using short range communication in an unlicensed spectrum (915 MHz). In this work, we have upgraded our cognitive controller with recently developed...
In this paper, we introduce the vibration acceleration signals combined with SCADA data to implement condition monitoring and fault diagnosis of the key components for wind turbines. Experimental data is from a wind turbine in six months with continuous SCADA data. Then three vibration models are established using the nonlinear state estimation technique (NSET) according to the SCADA data collected...
This paper focus on the development of a new device suitable to detect and measure methane gas in areas of natural gas storage site. This device, the Smart Gas Detection system, can measure the air and water quality, including all the parameters that can have outliers by an eventual gas leak in the aquifer or atmosphere. The air quality parameters measured by low cost sensors, include CH4 and CO2...
Drought occurs frequently in the world and it has great influence on the crops. Satellite remote sensing has been widely used in drought monitoring because of its wide range, fast information and short cycle. Temperature vegetation dryness index based on NDVI-Ts space is widely used to assess drought conditions. In this study, LAI-Ts space, constructed from MODIS MOD15A2 and MOD11A2 products, was...
This research aims to prototype a smart Lingzhi mushroom farm. This research applied the use of IOT with a sensor to measure and monitors the humidity in the Lingzhi mushroom farm. The humidity data processed through NETPIE was developed and provided by NECTEC as a free service for IOT. Humidity data was stored into a NET FEED (a sub service from NETPIE) and displayed on mobile devices and computers...
The monitoring of the ambient working conditions is a crucial part in occupational medicine. A wearable system for monitoring environmental conditions including physical and chemical parameters is introduced. The system operates based on an integrated and add on-board multi-layer sensors and fusion approach. It uniquely consists of only a small and light wrist-worn device which embeds a microcontroller...
The design of the system is based on ZigBee and the greenhouse environment is detected by a slave computer. The data collected will be transmitted to a host computer to do the specific operation. That is, by displaying and controlling greenhouse parameters in real time, the host computer can realize real-time monitoring and control of greenhouse temperature, humidity, light, air quality and other...
In tourism industry, a challenge is how to handle emergency situations during a journey. Although most of the tourism travel agencies focus on generating travel plans, an important part that has been ignored is to provide a creative emergency travel plan when a user meets an unforeseen situation during the journey. Thus, in order to address problems like this, the study to build a system that can...
China is a large agricultural country with the largest population in the world. This creates a high demand for food, which is prompting the study of high quality and high-yielding crops. China's current agricultural production is sufficient to feed the nation; however, compared with developed countries agricultural farming is still lagging behind, mainly due to the fact that the system of growing...
Medical wrist band, also known as medical identification tape, is a kind of wrist band, mainly used to mark the basic information of patients and help medical personnel to identify patients status. However, the traditional medical wrist has a single function, it cannot monitor the vital signs of patients. Based on the traditional medical wrist band, through the hardware facilities such as sensor and...
eHealth technology can bring a variety of benefits to patients, caregivers, and health institutions, by facilitating improved healthcare services through the utilization of Information and Communication Technologies (ICTs). The forthcoming generation of healthcare services will require advances in computing and Wireless Sensor Networks (WSNs) in order to leverage truly intelligent and adaptive features...
In this paper, we present a new loT-based health monitoring approach in which collected medical sensor data is sent to an analysis module via low-cost, low-power and secure communication links provided by a LoRaWAN network infrastructure. We mainly focus on monitoring blood pressure, glucose and temperature in rural areas where cellular network coverage is either absent or does not allow data transmission...
Physical unclonable functions (PUFs) take advantage of the effect of process variation on hardware to obtain their unclonability. Traditional PUF design only focuses on the analog signals of circuits. An arbiter PUF, for example, generates responses by racing delay signals. Implementations of such PUFs usually employ large area and power consumption while providing very low throughput. To address...
Internet of Things (IoT) can provide interconnection of things, which can promote the achievement of the remote human health monitoring. In this paper, a human health monitoring platform is designed and developed under the application framework of body sensor network of IoT. The platform can collect the physical information of user by constructing the human state acquisition system. And then the collected...
Keeping track of body's vital signals is essential for a healthy life. Even if you are young and healthy it is crucial to monitor your vital parameters. A real time portable wearable device is proposed to increase the accuracy and minimize the power consumption that measures up to 5 signals during activity or rest times, with a mobile application to display and save the data. Moreover, the data is...
The dense instrumentation of future smart buildings enables the implementation of advanced control techniques which are aimed at the dual objectives of energy efficiency/cost savings and occupant comfort. One of the essential functions and prerequisite consists of robust dynamic occupancy detection and prediction which allows improved estimation of active thermal zones and internal loads, as compared...
In order to efficiently manage the power consumption of communication devices, a management architecture is necessary to sense the working state of the equipment and the ambient environment. Therefore, it is important to properly select energy-efficient metrics that reflect the working environment. Then, on the basis of the metrics obtained, an optimal decision can be made and is followed by a reconfiguration...
In Internet of Things (IoT) environments, there are multiple sensors and devices monitoring different metrics and producing massive amounts of data. Monitoring of metrics can be done at different frequencies. Systems and applications that consume monitoring data typically use constrained IT resources, e.g., constrained network facilities, storage, display, processing/computing power, and energy. Given...
Proactive monitoring of one's health could avoid serious diseases as well as better maintain the individual's well-being. In today's Internet of Things (IoT) world, there has been numerous wearable technological devices to monitor/measure different health attributes. With the increasing number of attributes and wearables, it becomes unclear to individuals which ones they should be using. The aim of...
