Comparison between capacitive and microstructured optical fiber soil moisture sensors
Soil moisture content has always been an important parameter to control because it is a deterministic factor for site-specific irrigation, seeding, transplanting, and compaction detection. In this work, a discrete sensor ... -
Microstructured optical fiber sensor for soil moisture measurements
A discrete sensor based on a Sn0₂-FP (Fabry-Pérot) cavity is presented and characterized in real soil conditions. Results are compared, for the first time to our knowledge, with a commercial capacitive sensor and gravimetric ... -
Real time measuring system of multiple chemical parameters using microstructured optical fibers based sensors
In this paper, a multiplexing system for simultaneous interrogation of optical fiber sensors which measure different parameters is presented and validated. The whole system has been tested with 6 different sensing heads ... -
Relative humidity multi-point optical sensors system based on Fast Fourier multiplexing technique
In this paper, a new multipoint optical fiber system for relative humidity measurements based on Sn02-FP (Fabry-Pérot) sensing heads and an optical interrogator as single active device is presented and characterized. The ... -
Simultaneous and quasi-independent strain and temperature sensor based on microstructured optical fiber
In this paper, a new sensor system for simultaneous and quasi-independent strain and temperature measurements is presented. The interrogation of the sensing head has been carried out by monitoring the FFT phase variations ... -
SnO2-MOF-Fabry-Pérot humidity optical sensor system based on Fast Fourier transform technique
