Wavelet Transform Smoothing Filters for Metal Oxide Gas Sensor Signal Cleaning

This paper reports on a series of experiments to evaluate the methods for feature extraction and denoising the digital signal from thin film zinc oxide-tin dioxide composite gas sensor devices. The aim was to find a method that not only cleaned the signal but also maintained the shape, precision and resolution of the signal. It was found that the Savitzky–Golay smoothing filter method gave the best, smoothed and cleaned, approximation of the sensor response regardless of the thin film

TOWARDS A NEW GAS SENSOR MICROSYSTEM USING ELECTROACTIVE POLYMERS THIN FILMS

This paper describes the development of a new gas sensor device using some electroactive polymers in thin layers. The poly(fluoro-aluminium phthalocyanine) powder, (AlPcF)n, has been synthesized, then deposited by vacuum evaporation on alumina or silicon substrates in the form of thin films with control of the deposition rate. (AlPcF)n thin layers are doped by NO2 or O2 diluted at various concentrations in N2 and their conductivity variations are studied as a function of time, temperature and

tea-taster like scores. It has been observed that pre-processing of gas sensor data improves the classification accuracy and in this paper, a comparative study of different normalization techniques is presented for black tea application using electronic nose. For this study black tea samples were collected from different tea gardens in India. At first Principal Component Analysis (PCA) is used to investigate the presence of clusters in the sensors responses in multidimensional space. Then

The main methodology of the device is to monitoring the vehicle speed via Ethernet shield through Internet of things. The protective system is maintained by analysing gas tank through gas sensor which details about the gas leakage. The advantages of this device are alarming the driver when there is any gas leakage in the vehicle and also informs about the speed of the car. A

Fluctuation enhanced gas sensing using UV irradiated Au-nanoparticle-decorated WO3-nanowire films

WO3 nanowires (WO3-NWs) decorated with gold nanoparticles (AuNPs) were utilized in resistive gas sensor devices to detect ethanol by use of fluctuation enhanced sensing (FES).  The experimental system records both DC resistance and fluctuations of the sensing film. Our data verify that the sensitivity and selectivity of the gas sensor are improved by applying FES when the sensor is stimulated with a combination of UV light and heating. We conclude that UV light can produce improved gas

CO2 sensing characteristics of Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) nanostructured thick film

SmCoO3 gas sensor has been developed with high sensitivity for CO2 gas by doping Ba. Nanostructured SmCoO3 and Sm1-xBaxCoO3 (x = 0, 0.1, 0.15, 0.2) were obtained by EDTAGlycol method. The operation temperature falls and sensitivity increases from 425 to 370OC when Ba concentration in SmCoO3 changes from x = 0 to x = 0.1. Ag impregnation over Sm0.9Ba0.1CoO3 sensor, on exposure to CO2 at about 360OC showed an increased sensitivity as well as the response time also decreases. The possible CO2
