A Hetero-core Spliced Optical Fiber Sensor Network for Remote Monitoring of Agricultural Enviroment

This paper describes an integration of hetero-core spliced optical fiber sensor network for remotely monitoring agricultural environment with a cloud service. A hetero-core spliced optical fiber SPR sensor introduced in our study is able to provide both data communications and sensing functions in the same fiber line simultaneously. Our study uses a fiber sensor covered with Tantalum Pent oxide (Ta2O5) that allows the data transmission distance to be extended with a wavelength of 1310nm for a wide area monitoring. Our novel sensor system can gather remotely-observed environmental data from the monitoring points and deliver them to an operator on a real-time basis.
