Abstract
An optical spectral sensing device for determining at least one property of a fluid. The device has an elongated porous body, a first end and a second end, a solid-state optical emitter at the first end of the body oriented to emit radiation toward the second end of the body, and a solid-state optical detector at the second end of the body oriented to detect radiation emitted by the optical emitter and to output a signal responsive to absorption of radiation. The device is configured to determine depth of a fluid based on the signal output by the optical detector.
