To maximize the energy productivity, effective in-field detection and real-time control of defective thermoelectric modules (TEMs) are critical in constituting a thermoelectric generation system (TEGS). In this paper, autonomous and distributed sensor nodes are designed to implement the wireless TEM management in terms of the measurement criteria of defective TEMs formulated for series-parallel-connected...
This paper reviews current progress in the area of wireless microwave acoustic sensor technology, and discusses advances in wireless interrogation systems that can operate in harsh environments. The use of wireless, battery-free, low maintenance surface acoustic wave (SAW) sensors has been successfully demonstrated in applications including high temperature turbine engines and inflatable aerospace...
A packaged wireless multisensor module has been developed and used for monitoring variations of temperature and humidity in reinforced concrete (RC). The multisensor (Sensirion, SHT 75) integrated a microprocessor control unit (MCU) and radio frequency integrated circuits (RFIC) for wireless signal transmission was packaged using poly(methyl methacrylate) (PMMA) to protect the module for avoiding...
Forest fires have drawn increasing attention in recent years due to their tremendous effects on environment, humans and wild life, ecosystem function, weather, and climate. Accurate monitoring of forest fires field is important since it contributes in fire effects assessing and controlling. This study attempts to apply adaptive weighted fusion algorithm in a wireless sensor networks (WSNs) system...
The effectiveness of ECG monitors can be significantly impaired by motion artefact, which can cause misdiagnoses, lead to inappropriate treatment decisions, and trigger false alarms. However, it is difficult to separate the noise from bio-signal due to its frequency spectrum overlapping that of the ECG. In this paper, we developed a wireless multi-sensor device for physiological signal monitoring,...
The system was designed for sensor measurement and data transfer. A new architecture of a multisensor system for temperature measurement using wireless communications was used in the paper. There are used sensors with digital or analog outputs. The control software of the system has been created. Different software were designed for wireless units. The integrated RF chip nRF9E5 was used as wireless...

Dissolved oxygen (DO) is an important indicator of the water quality in the modern sewage treatment It reflects the degree of self-purification capacity of the water. In this paper, we proposed a kind of wireless sensor network-based dissolved oxygen online collection terminal. The terminal, with the core of ARM (Advanced RISC Machines) microprocessor, combines of multi-sensor data fusion technology...
