A sensor system, apparatus, and method. The sensor system can include a mobile unit and a sensory head having a power source, wherein the sensory head is releasably coupled with the mobile unit. The sensory head includes at least one sensor that measures one or more characteristics of a test piece. The sensory head is placed in proximity to the test piece, then detached from the mobile unit. While the sensory head is detached from the mobile unit, the at least one sensor can measure the one or more characteristics of the test piece. Measurement date is then uploaded to a remote device. Once measurements are completed, the sensory head is attached to a mobile unit and detached from the test piece. Thus the sensor system, apparatus, and method can measure the characteristic over a period of time while the sensory head is detached from the mobile unit.
