A lateral motion sensing assembly for sensing movement experienced by a structural member such as a support beam or driven pile. The sensing assembly is immersed within a casing which is mounted to the structural member. The sensing assembly includes a support body and an accelerometer mounted to the support body for measuring movement of the structural member. The accelerometer is aligned with an anticipated line of motion such that measurements can be made along this line of motion. A pair of lever arms are pivotally mounted to the support body for removably securing the support body within the casing. A spring is mounted between the support body and lever arms for continuously biasing the lever arms to a position perpendicular with the support body.
