—Stream temperature regimes are fundamentally important to understanding patterns and process in aquatic ecosystems and inexpensive digital sensors enable accurate and repeated measurements of temperature at a site. Most temperature measurements in mountain streams are made only during summer months because of logistical constraints associated with stream access and concerns that large annual f...

zno and zno: mn nanocrystals were synthesized via reverse micelle method. the structural properties of nanocrystals were investigated by xrd. the xrd results indicated that the synthesized nanocrystals had a pure wurtzite (hexagonal phase) structure. resistive gas sensors were fabricated by providing ohmic contacts on the tablet obtained from compressed nanocrystals powder and the installation ...

Temperature is a principle parameter that needs to be monitored and controlled in most food processing operations such as heating, cooling, drying and storage. Temperature sensors have been developed based on different temperature-dependent physical phenomena including thermal expansion, thermoelectricity, electrical resistance, and thermal radiation. Temperature sensors used in agricultural an...

Low-temperature electronics operating in below zero temperatures or even below the lower limit of the common -65 to 125 °C temperature range are essential in medical diagnostics, in space exploration and aviation, in processing and storage of food and mainly in scientific research, like superconducting materials engineering and their applications-superconducting magnets, superconducting energy ...

A clustering method is an effective way to select the proper temperature sensor location for thermal error modeling of machine tools. In this paper, a new temperature sensor clustering method is proposed. By analyzing the characteristics of the temperature of the sensors in a heavy floor-type milling machine tool, an indicator involving both the Euclidean distance and the correlation coefficien...

The performance of inertial MEMS sensors – gyroscopes and accelerometers – depends heavily on the operating temperature. That is, their accuracy will degrade dramatically with rising temperature. In this paper the errors of inertial sensors as a result of varying temperature will be first modelled. The accuracies obtained with constant and varying temperatures will be compared and analysed. The...

A smart temperature sensor is an integrated system consisting of a temperature sensor, its bias circuitry and an analog-to-digital converter (ADC). When manufactured in CMOS technology, such sensors have found widespread use due to their low cost, small size and ease of use. In this paper the basic operating principles of CMOS smart temperature sensors are explained and the stateof-the-art is r...
