“…The determination of hazardous hydrogen concentration in air (4.65-93.9 vol%) is an important issue in many areas of human activity [3]. Therefore, there is strong interest in developing wide bandgap semiconductor, like GaN (3.4 eV), hydrogen gas sensors which retain their semi-conducting properties and can be still operated at higher temperature ranges [4][5][6][7][8].…”

“…That capacitance value can be measured by means of an electronic evaluation system. A current moisture value is ascertained with the measured capacitance value, using further parameters such as temperature and comparative parameters [13,14]. Humidity sensing elements of the capacitance sensing type usually include a moistureinsensitive, non-conducting structure with appropriate electrode elements mounted or deposited on the structure along with a layer or coating of dielectric, highly moisture-sensitive material overlaying the electrodes and positioned so as to be capable of absorbing water from the surrounding atmosphere and reaching equilibrium in a short period of time.…”

Wireless Sensor Networks (WSN) is now widely used in precision agriculture applications. Sensors play an important role in WSN.The traditional humidity sensors employed in the agriculture have a drawback that they acquire a large amount of data which is to be transmitted or processed. Whereas the intelligent sensor proposed in this paper uses a conventional sensor and an embedded processor that can process the data acquired using algorithms to reduce the amount of data collected, to extract only relevant information and to present this information in a format which minimizes post-processing latency. As a result of which the final processing end has to perform a little computation that too only on features (like significant changes in humidity) rather on the huge data hence reducing the power consumption. The intelligent humidity sensor reduces the amount of data processed by 50% (depending upon humidity variations) and thereby also reducing the power consumption.
