An autonomous Internet of Things (IoT) wireless sensor network (WSN) powered by a solar energy harvester with low power electronics is presented in this paper. The power supply is a critical challenge for IoT sensors as many of them normally have limited lifetime due to the battery with limited capacity used. The WSN system, sensor node electronics, and the energy harvesting techniques are all configured...
Smart Irrigation Decision Support (SIDS) system based on fuzzy logic using Wireless Sensor Network (WSN) is considered for precision water irrigation. WSN consists of limited-energy sensor nodes which are equipped with sensing, wireless communication and processing capabilities. SIDS aims to measure the agricultural parameters including the soil temperature and soil moisture using the sensor nodes...
This paper proposes a system to monitor, through the internet, the data of a logistics distribution truck. For this, it was implemented a reliable and flexible wireless sensor network with low energy consumption. The technology used for the radio system was Bluetooth Low Energy (BLE). Each node in the network contains one type of sensor. The sensors information together with GPS and On-Board Diagnostics...
Wildfires, often dubbed megafires, have in recent times increased in both frequency and scale, owing largely to human error as well as climate change. Due to their uncontrolled unpredictable rapid growth and behaviour, they can quickly become difficult to contain, leading to significant loss of lives, wildlife and property. It is therefore critical to tackle such fires in the early stages. This demands...
The use of Wireless sensor network is to monitor an area for event detection. The sensor node have some limitation like the sensor node associated with battery power and generally it is not possible to recharge or replace battery of sensor due to large number of sensor node, node distribution in remote, desert or hostile areas etc. The energy consumption of sensor node appears a lot of challenges...
Environmental temperature is essential for security monitoring and controlled areas, such as chemicals factory and Inflammable goods vehicle, in which WSN is the most appropriate choice for intelligent monitoring purpose. In this work, we design a piezoelectric energy harvester to collect low-acceleration (<0.5 g) and low-frequency (<50 Hz) vibration energy for powering wireless sensor network...
In this paper, an innovative design and development process is presented for a Wireless Sensor Network (WSN) prototype aimed at detecting and monitoring forest fires at the Guanguiltagua Park located in the Metropolitan District of Quito (DMQ), capital of Ecuador. Every year the city of Quito is affected by recurrent forest fires, especially in summer time where high temperatures and soil dryness...
Wireless sensor network become the most important part in any technology that need to monitor the environment. One of the new trends that need wireless sensor network is military applications. Some of the previous studies used Bluetooth module to send the measured weather factors wirelessly from the weather factors monitoring system to the central station. The problem of using Bluetooth module is...
In this work, we propose the development of monitoring system for the Air Handling Unit of a particular building of the University via Zigbee network. The proposed system will provide all the essential information required for the thermal modeling of the building using Dynamic Thermal Simulation. Furthermore, this will allow us to accomplish autonomous building management and also to study the thermal...
The wireless sensor network (WSN) represent a fertile area for research and exploration, especially with the enormous development in modern electronic systems, where it becomes an alternative to traditional wired systems. The wireless systems are less energy-consumptive and inexpensive, in addition, it helps to reduce the complexity of wiring. Wireless sensor networks require the design of high density...

There is a rapid growth in wireless communication devices, such as Wireless Sensor Nodes (WSN). While WSN has the abilities of sensing, processing and communication over distances, its abilities are limited by the capacity of its battery. To use the full functionalities of WSN, either the battery needs to replace or recharge in a periodically manner. However both solutions are not convenient for livestock...
