Abstract

Nano gas sensing technology finds its importance where gas sensors used for detecting the toxic gases have been fabricated and modified gradually to enhance its sensitivity and selectivity. Timely and precise monitoring of flammable and hazardous gases inside the mines can aid preventing accidents. Previously Graphene mono-layer has been used as sensing material along with addition of Gold nano-particles on its surface as a sensor device. Various wired and wireless communication with the sensor nodes like Zigbee protocol, IBM Bluemix have been established in recent past and implemented with Internet of Things (IoT)but with limitations. In this paper fabrication of Au based TiO2, CuO, ZnO, WO3 resistive type gas sensors array using sol gel method is proposed for better conduction and Node MCU(ESP8266)is employed as a Wireless Fidelity (WiFi)module in this study which when implemented using Message Queuing Telemetry Transport (MQTT)protocol ensures better efficiency and speed. With increased sensitivity, selectivity and better efficiency the paper aims in resulting a better mine hazard management system.

纳米结构气体传感装置及其在地下矿山中的应用

纳米气体传感技术的重要性在于，用于检测有毒气体的气体传感器已经被制造出来，并逐渐被改进以提高其灵敏度和选择性。及时准确地监测矿井内的易燃有害气体有助于防止事故的发生。在此之前，单层石墨烯被用作传感材料，并在其表面添加金纳米颗粒作为传感器件。与传感器节点的各种有线和无线通信，如Zigbee协议，IBM Bluemix在最近的过去已经建立并实现了物联网(IoT)，但有局限性。本文提出了采用溶胶凝胶法制备Au基TiO2、CuO、ZnO、WO3电阻型气体传感器阵列，以获得更好的导电性，并采用Node MCU(ESP8266)作为无线保真度(WiFi)模块，采用消息队列遥测传输(MQTT)协议实现，保证了更高的效率和速度。本文旨在提高灵敏度、选择性和效率，建立一个更好的矿井危害管理系统。
