This paper presents the development of an energy efficient environmental sensor that sends measurement data to a cloud platform using HTTP (Hypertext Transfer Protocol) requests. The device is based on a programmable system-on-chip (PSoC), and is equipped with a temperature and relative humidity sensor for taking measurements and with a WLAN (wireless local area network) module for sending data to...
Implementation of precision apiculture methods into practice is highly depended on availability and cost-effectiveness of honey bee monitoring equipment. Expenses of monitoring system installation and maintenance activities also should be minimized. In order to successfully predict different bee colony states like: swarming, determine nectar collection activity and health of honey bees both in active...
Our work has developed the Internet of Things (IoT) LoRa prototype to support the remote measurement of temperature at the frequency of 915 MHz. The device is structured by a temperature sensor, memory storage, data processing and data visualization using Cloud Server on the Web Browser. The performance is evaluated by both LoS and Non-LoS field trial of 14 dBm transmit power. By using the IoT platform...
Internet of Things (IoT) is a new technological paradigm that can connect things from various fields through the Internet. For the IoT connected healthcare applications, the wireless body area network (WBAN) is gaining popularity as wearable devices spring into the market. This paper proposes a wearable sensor node with solar energy harvesting and Bluetooth low energy transmission that enables the...
Wireless sensor networks (WSNs) have been adopted as merely data producers for years. However, the data collected by WSNs can also be used to manage their operation and avoid unnecessary measurements that do not provide any new knowledge about the environment. The benefits are twofold because wireless sensor nodes may save their limited energy resources and also reduce the wireless medium occupancy...
Living conditions in any country are important, especially a local environment is more important to many people. The parameters like a noise level, light intensity, barometric pressure, carbon monoxide (CO) and carbon dioxide (CO2) concentration levels are monitored to evaluate living conditions. The mentioned reasons led to the practical realization of Wireless Unit for Environmental Monitoring (WUEM)...
In this paper, we focus on two methods that can be used to increase the resilience of remotely-deployed and unattended IoT devices that must operate without direct human intervention. The methods include adaptive messaging rates for power-constrained devices where the most energy intensive process involves the transmission and reception of data via wireless means, and data caching and replay for extended...
