Research and Practice of New Gas Sensors Based Materials on Internet of Things

Abstract:

The development of Internet of Things has led to a sharp rise in demand for sensors. Users require that sensors can collect information from the Internet of Things in a timely and accurate way. In response to the present situation that there are only a few varieties of gas components-based materials in the application of Internet of Things. According to the new viewpoint that energy gap Eg> 2ev materials are likely to be used to develop thin film gas sensors, we have succeeded in preparing quality thin film gas sensors Fe₂O₃/2%CeO₂ and TiO₂/2%CeO₂ by using the method of powder sputtering. Based on the concept of metal oxide Eg chemical bonds, we have successfully prepared ZnSnO₃ and other composite gas sensor-based materials. All these are significant in guiding the development of new gas sensor-based materials for Internet of Things sensors. This paper focuses on what we have done and how we have down in new gas sensors based materials research and practice of Internet of Things
