A motion sensing device for sensing infrared rays includes a substrate; an optical module, including a first spacer layer coupled to the substrate; a first glass layer formed on the first spacer layer; a second spacer layer formed on the first glass layer; a second glass layer formed on the second spacer layer; a third spacer layer formed on the second glass layer; a first lens bonded on a first side of the second glass layer; and a second layer bonded on a second side relative to the first side of the second glass layer; and a coating layer covering the optical module for shielding against infrared rays, wherein the coating layer does not cover the first lens. |
