Alexander Hetznecker TUD

0 ≤ x ≤ 3) was used as a model for solid electrolyte additives. The structure of that material is ideally suitable for studies of the correlation between material parameters and the gas sensitivity of the layers. In the NASICON structure the content of mobile Na+–ions can be varied by a factor of four resulting in a simultaneous change of the ionic conductivity σ(Na+) by approximately ...


Configure and read out the Raspberry Pi gas sensor (MQX)

Configure and read out the Raspberry Pi gas sensor (MQX) Sensors are necessary to detect the components of the air. These are used in smoke detectors. However, instructions for using these gas sensors at the Raspberry Pi are rare, which is why in this tutorial the general use of such MQ modules at the Raspberry Pi is shown.

GAS Sensor Modelling and Simulation: Science Engineering ...

In this study, a new model for the gas sensor based on the gradient of GNR conductance as a function of gas concentration has been provided and a FET based structure as a modelling platform is suggested. Lastly, the proposed model is evaluated through a comparison study between model and experimental result. The graphene gas sensor is able to operate under ambient conditions and at room ...


PBSens ETheses

Nanowire Gassensoren können weitreichend angewandt werden, wie im Gesundheitsbereich, Sicherheitsbereich, und der Umweltüberwachung. Das größte Problem welches Forscher beschäftigt ist die mangelnde Selektivität und die mangelnde Kenntnis über die Reaktionen welche an der Oberfläche des Gassensors auftreten. Wir präsentieren in dieser Masterarbeit ein mathematisches Model für ...

Siloxane treatment of metal oxide semiconductor gas ...

The classical model for a gas sensor’s sensitivity is based on energy barriers at grain–grain boundaries resulting from surface charges in the form of O 2 and O and the mass action law (Madou and Morrison, 1989). Therefore, the steadystate sensitivity to a certain gas is given by the equilibrium between oxygen oxidizing the sensor surface, e CO2 k1! and k1 O 2; (1) e CO 2 2 k! 2O ; (2 ...
