Abstract
A sensor assembly includes one or more accelerometers that generate movement signals indicative of movement of a powered system, a fluid level sensor that generates fluid level signals indicative of an amount of fluid in the powered system, and one or more processors that receive the movement signals and the fluid level signals. The one or more processors also (a) filter at least some of the movement signals based on a speed at which the powered system operates and/or (b) calculate one or more of (1) a statistical measure, (2) a fast Fourier transform (FFT), or (3) a discrete Fourier transform (DFT) of the movement signals. The assembly also includes a first antenna that wirelessly communicates the one or more of the movement signals, the amount of fluid, the statistical measure, the FFT, or the DFT to a remote location.
