| Research Abstract |
The overall concept of our study is to construct a sensor network which could be utilized in the wide area of environmental monitoring with fiber optic sensor. Focusing on the realization of a fiber optic sensor system, this research objective is to construct a remote monitoring network for soil gravity water in agricultural environments. The study involves the installation of multipoint sensors into the same fiber line and differentiates the response from each sensor by using the internet-standard protocol, Simple Network Management Protocol (SNMP). In order to extend the distance of data transmission for large-area monitoring, the study used an HC-SPR sensor coated with Ta2O5 and adopted a wavelength of 1310 nm. To distinguish the status of multi-point sensors and to construct remote data acquisition sensor networks, a method that uses SNMP is introduced. In a nutshell, the objectives of the study has been achieved and all defined requirements has been met with the proposed method.
