A fiber Bragg grating sensor arrangement includes a resonant cavity light emitting diode for outputting light; a fiber having a first end disposed to receive light output from the resonant cavity light emitting diode, the fiber including fiber Bragg grating etched at one or more locations along a length thereof. A strain mount or beam supports the fiber and to which the fiber is attached or bonded. A light detection circuit disposed at a second end of the fiber receives light traveling through the fiber, the light detection circuit sensing intensity of the received light that corresponds to strain or force applied to the fiber that is bonded to the strain mount. Another fiber Bragg grating sensor arrangement includes a second reference fiber that does not receive a force or strain. The reference fiber provides an output used to prevent temperature/humidity from affecting the output of the FBG sensor arrangement.
