Abstract
Polyimide coated fiber Bragg gratings have a linear response to changes in relative humidity and temperature. Blue Road Research is using this technology to monitor relative humidity and using acrylate-coated gratings to monitor temperature. This paper describes some of the sensors and readout systems for simple and multiplexed relative humidity and temperature sensors. Additionally, an indirect method for monitoring soil moisture is described.
