“…Their possible integration with other energy harvesting technologies was also investigated; for example, for increasing the overall efficiency of photovoltaics [8] by exploiting the thermal gradient between the back of the panels and the ambient temperature, hence recovering the otherwise dissipated heat. The inherent restrained necessity of maintenance and the high long-term efficiency, make TEGs a valid alternative to batteries in providing an autonomous source of energy to sensor nodes [9,10,11] or entire Wireless Sensor Networks [12,13,14,15,16]. …”

“…The focus is on using an appropriate procedure and suitable hardware to investigate the underlying relationship between both the operating temperature, the temperature difference and the parameters of the electrical and thermal equivalent model for commercial modules. The novelty consists in applying a proper current stimulus (for which two alternatives are discussed) to the TEM under test and simultaneously acquire both thermal and electrical data to automatically derive all parameters in a single test, without using either a discrete load [9,23,24] nor hot plates or auxiliary TEMs [2,11,17,24,25,26,27,28,29]. Unlike other approaches, the developed testbed permit, using a very simple configuration, to quickly obtain all relevant parameters, making possible an extensive TEM characterization over a wide range of temperature differences, ambient temperatures and electric loads.…”

Thermo-Electric Modules (TEMs) are being increasingly used in power generation as a valid alternative to batteries, providing autonomy to sensor nodes or entire Wireless Sensor Networks, especially for energy harvesting applications. Often, manufacturers provide some essential parameters under determined conditions, like for example, maximum temperature difference between the surfaces of the TEM or for maximum heat absorption, but in many cases, a TEM-based system is operated under the best conditions only for a fraction of the time, thus, when dynamic working conditions occur, the performance estimation of TEMs is crucial to determine their actual efficiency. The focus of this work is on using a novel procedure to estimate the parameters of both the electrical and thermal equivalent model and investigate their relationship with the operating temperature and the temperature gradient. The novelty of the method consists in the use of a simple test configuration to stimulate the modules and simultaneously acquire electrical and thermal data to obtain all parameters in a single test. Two different current profiles are proposed as possible stimuli, which use depends on the available test instrumentation, and relative performance are compared both quantitatively and qualitatively, in terms of standard deviation and estimation uncertainty. Obtained results, besides agreeing with both technical literature and a further estimation method based on module specifications, also provides the designer a detailed description of the module behavior, useful to simulate its performance in different scenarios.

“…SCADA is one of the sophisticated technology, some problems mentioned ealier may raise for the implementation in developing countries. A telemetry system based on Web interafece is proposed to measure the temperature can be seen in [9] on the hot steam diverter pipe via Radio-Frequency Identification (RFID) with short measurement range and in [10] on the high-voltage equipment. Similar to the web-SCADA, these systems also need server to support the Web.…”

“…Wireless sensor networks (WSN) (Romer et al, 2004;Akyildiz et al, 2008) are developed using autonomous sensor nodes (Dalola et al, 2009) to collect remote sensor data for decision systems with low power consumptions and failure tolerable mechanisms. In general, the WSN system can be applied to the factory automation , intelligent diagnosis , intelligent monitoring and control systems (Sridhar et al, 2007), smart home (Suh et al, 2008), etc.…”
