A humidity sensor and method is disclosed. The sensor is configured as an optical fiber based sensor and may be useful in obtaining moisture information, such as humidity and/or relative humidity (RH) in curing concrete. The sensor may be configured to isolate the sensor from external mechanical stresses, chemical reactions and/or temperature fluctuations that may occur in the concrete and/or at least account for such occurrences. Methods of calibrating the sensor are also disclosed. The sensor may be configured as a fiber Bragg sensor.
