This paper proposes a detection scheme for reactions of optical fiber sensors and shows experiments and results to identify sensor conditions with Simple Network Management Protocol (SNMP) as the Internet standard protocol. Optical Sensory Nerve network (OSN) with optical fiber sensors has been developed in order to alleviate issues on wireless sensor networks about battery lifetime and data communication. Moreover, a method to gather sensed information with SNMP and a commercially available device has been devised; however, this method holds issues on limited performance. Thus, this paper demonstrates the detection scheme using original SNMP agent software and experiments utilizing two types of sensors (binary switch sensors & mat sensors). The SNMP agent software allows to increase the number of sensors which can be detected and installed in OSN.

“…In reference [19], anelastic properties of LGS and LGT have been studied for high temperature operation, targeting frequency control and mass deposition devices. Langasite crystals and devices have been exposed to abrupt shocks in temperature and pressure, and to turbine engine vibration environments without compromising the material integrity [20] [21].…”

Microwave acoustic devices have long been shown to provide sensitive platforms for physical and gas sensors. Piezoelectric substrates introduced over the past two decades, such as the langasite (LGS) family of crystals, gallium orthophosphate, and aluminum nitride have enabled the exploration of microwave acoustics sensing at temperatures above 500°C. However the ability of the substrate to withstand high temperatures is only one of the requirements for sensor operation in harsh environments. Other prerequisites are: the development of stable high-temperature device electrodes; appropriate packaging; and resilience of the entire system to thermal shock and thermal cycling. In this paper, the wireless operation of microwave acoustic wave sensors in harsh environments is reviewed, and recent achievements are highlighted. Particular focus is given to surface acoustic wave (SAW) sensor technology because it has the advantage of being wireless, battery-free, and allows interrogation of arrays of multiple devices. During the last decade, wireless hostile environment microwave acoustic sensors that can detect gases and monitor temperature and pressure have transitioned from laboratory proof-of-concept to commercial devices and systems. Recent accomplishments in thin film technology and packaging are extending the technology to even higher temperatures, beyond 1000°C. These technological advances are enabling wireless microwave acoustic sensor applications in hostile environments including power plants, turbine engines, oil/gas refineries, and high temperature industrial processing.
