摘要

基于半导体金属氧化物(如SnO2)的气体传感器已被发现在探测各种气体方面非常有用。气体与半导体金属氧化物制成的传感层表面的可逆相互作用是传感器电阻变化的原因,传感器电阻通常用作传感器响应的度量。半导体气体传感器是市售的,并应用于许多气体检测系统。它们可靠、小巧、坚固且价格低廉。然而,有一些问题限制了这种传感器的广泛使用。半导体气体传感器通常表现出低选择性、漂移性和低重复性,温度和湿度对传感器性能的影响较大。工作温度的不稳定性是影响传感器响应的因素之一,在实际测量中应予以考虑。在这项工作中,一些实验结果证明了环境温度如何影响传感器的工作温度。提出了一种通过控制传感器加热器电压来稳定传感器温度的方法。所有的测量都是在专用的测量台上进行的,由几个台式测量仪器组成。

Influence of operation temperature instability on gas sensor performance
Gas sensors based on the semiconducting metal-oxides, such as SnO2, have been found to be very useful for detecting a wide range of gases. The reversible interactions of the gas with the surface of the sensing layer made of semiconducting metal-oxides are responsible for changes of sensor resistance which is usually used as a measure of sensor response. Semiconductor gas sensors are commercially available and applied in numerous gas detection systems. They are reliable, small, rugged and inexpensive. However, there are a few problems limiting the wider use of such sensors. Semiconductor gas sensor usually exhibits a low selectivity, a drift and low repeatability of the response, strong influence of temperature and moisture on sensor properties. Instability of operating temperature is one of the factors that influence sensors response and should be taken into consideration during real life measurements. In this work some experimental results demonstrating how ambient temperature affects sensor operating temperature are presented. An approach to stabilize sensor temperature by controlling sensor heater voltage have been proposed. All measurement are performed with dedicated measurement stand consisting of few bench measuring instruments.
