چکیده
This paper presents design and assembly of mixed electronic circuitry for measured signal processing of the capacitive difference pressure sensor, as well as analysis of the obtained results. The smart pressure sensor provides values of measured pressure via 4 20 mA current loop output. The loop current is also used for sensor circuitry supplying. This means that current consumption of the whole sensor electronics should be less than 3.5 mA even in extended industrial temperature range from –40 to +125 °C.

Buckling Analysis of FG Plate with Smart Sensor/Actuator
In this paper, the active buckling control of smart functionally graded (FG) plates using piezoelectric sensor/actuator patches is studied. A simply supported FG rectangular plate which is bonded with piezoelectric rectangular patches on the top and/or the bottom surface(s) as actuators/sensors is considered. When a constant electric charge is imposed, the governing differential equations of mo...
متن کاملA Mobile Smart Care platform Home spirometry by using the smartphone microphone
Mobile health (mHealth) applications are increasingly seen as cost-effective alternatives for hospital care. In this paper, it is investigated whether a smart phone microphone-based application can replace a more common differential-pressure spirometry sensor. Moreover, we investigate the steps that are needed to implement an application that uses a sensor to mimic another sensor, for which its...
