Abstract
A non-contact type electronic level sensor includes a light source, a vial, a photosensitive element, and an image processing unit, wherein the vial has a bubble located at a position able to receive the light emitted from the light source, the photosensitive element is located at a position opposite to the mentioned bubble and keeps a fixed distance from the ial in order to form the image of the vial bubble, the image processing unit is electrically connected to the photosensitive element and transfers the bubble image into an electronic level signal by comparing the centroid of the bubble image and a preset point.
