Environmental inspection is very significant in agriculture because it helps the producer determine optimal input distribution and reduce the adverse effects on the environment. Conventional approaches do not have adequate spatial and temporal resolution for effective actions. This paper introduces a new concept in the monitoring of the environment in agriculture using an analysis of the physical properties of optical fiber sensors. The sensor has some advantages like no vulnerability to electromagnetic interferences, is more sensitivity, and can operate in destructive environments. The aimed system entails rainfall, temperature, humidity, and soil moisture checks, in addition to checkpoints stationed through fiber optics across the agricultural field. The comments obtained from the sensors are then assessed to offer information on environmental conditions and surroundings within a limited duration of time. The information generated by these sensors can be effectively applied for purposes of adjusting irrigation and watering, as well as, the use of fertilizers and a range of other factors that can influence the outcome of crop production, and thus, the results related to savings of resources. The investigation also involves simulation and performance evaluation of the intended optical fiber sensor system and two modulation approaches. The study proves that optical fiber sensors are reliable and can be of great benefit to conserving the environment in the use of agriculture.
