Claim:
1. A method comprising: receiving, by at least one processing device, a signal associated with a measurement of a property of an object by one or more sensors disposed in a belt of a conveyor belt system; examining, by the at least one processing device, one or more parameters of a signal conditioning circuit to determine whether clipping of the signal has occurred, the signal conditioning circuit comprising a micro-electro-mechanical system (MEMS) based capacitor, a charge amplifier and a second capacitor electrically coupled to the MEMS based capacitor, and at least one resistor in parallel with the MEMS based capacitor; upon a determination that clipping of the signal has occurred, changing, by the at least one processing device, a capacitance of the MEMS based capacitor to decrease a gain of the signal conditioning circuit; upon a determination that clipping of the signal has not occurred, determining, by the at least one processing device, whether a cut-off frequency of the signal conditioning circuit is within a range of a frequency response of the object measured by the one or more sensors; upon a determination that the cut-off frequency of the signal conditioning circuit is not within the range of the frequency response, changing, by the at least one processing device, the capacitance of the MEMS based capacitor to change the cut-off frequency of the signal conditioning circuit; upon a determination that the cut-off frequency of the signal conditioning circuit is within the range of the frequency response, determining, by the at least one processing device, whether a voltage of the signal indicates that a dynamic range of the one or more sensors is low; and upon a determination that the voltage of the signal indicates that the dynamic range of the one or more sensors is low, increasing, by the at least one processing device, a resistance or a capacitance of the signal conditioning circuit.
