Household nowadays need to face the global warming and also have increase in cost of living. In this era also, especially Malaysia is one developer country, so there many developments. So situation can lead crises household for example dust, high temperature, increasing electrical bill. This study was aimed develop solar exhaust fan with temperature sensor that help overcome issue. The project ...

This paper proposes the strategy of fabricating an all fiber wide-range displacement sensor based on the macro-bend coupling effect which causes power transmission between two twisted bending plastic optical fibers (POF), where the coupling power changes with the bending radius of the fibers. For the sensor, a structure of two twisted plastic fibers is designed with the experimental platform th...

Many researchers propose dedicated hardware [1, 2] to process sensor data on mobile systems, reducing the burden on generalpurpose computing units and increasing a system’s energy eciency. However, these hardware units are placed at a distance from sensors, thermally isolated to avoid an increase in thermal noise of sensors that can degrade the €delity of the sensor output signal. In this post...

A precision CMOS chopping amplifier is adopted in this work to improve a CMOS temperature sensor high sensitive enough for intracranial temperature monitoring. An amplified temperature sensitivity of 18.8 ± 3*0.2 mV/C is attained over the temperature range from 20 C to 80 C from a given 10 samples of the same wafer. The analog frontend design outputs the temperature dependent and the temperatur...

Variation in temperature is a common phenomenon which can affect the performance factor of any device used at different temperatures. Temperature sensors are used to identify the variation in temperature at various or same places as temperature can vary according to time at same place also. This work is related to making Temperature sensor Design on Virtex6 Field Programmable Gate Array for Low...

This work analyses the performance of MOSFETs as a temperature sensor for the measurement of AC on-chip thermal signals caused by a power-dissipating circuit under test (CUT). First, we characterize how the CUT-sensor thermal coupling depends on the frequency of the AC thermal signal and the CUT-sensor distance. Second, we characterize how the thermal sensitivity of the sensor depends on the bi...

Although the numerous advantages of polymer optical fibers have been exploited in the fields of sensors and telecommunications, such fibers still experience a critical problem: the temperature dependency. Therefore, we explored the temperature-independent operation of a polymer fiber-optic evanescent wave sensor immersed in distilled water. We investigated variations in the surface morphology, ...

A low-power temperature-sensing oscillator was developed using a 0.35m standard CMOS process. This oscillator generates a clock pulse whose frequency is proportional to absolute temperature (PTAT frequency). It consists of a PTAT current generator controlled with an external reference clock and a frequency-locked loop biased with an external reference voltage. The PTAT current generator makes u...

This Technology Installation Review describes the installation of a wireless temperature sensor network at the U.S. Environmental Protection Agency (EPA) National Health and Environmental Effects Research Laboratory in Duluth, MN. The objective of the wireless sensor demonstration was to showcase the technology so the experiences with the technology and benefits of the project may be replicated...
