An omnidirectional tilt and vibration sensor contains a first electrically conductive element, a second electrically conductive element, an electrically insulative element, and a pair of electrically conductive weights. The first electrically conductive element has a first diameter on a proximate portion of the first electrically conductive element and a second diameter on a distal portion of the first electrically conductive element, where the second diameter is smaller than the first diameter. The second electrically conductive element has a first diameter on a proximate portion of the second electrically conductive element and a second diameter on a distal portion of the second electrically conductive element, where the second diameter is smaller than the first diameter. In addition, the electrically insulative element is connected to the first electrically conductive element and the second electrically conductive element, where the second distal portion of the first electrically conductive element fits within a proximate end of the electrically insulative element, where the distal portion of the second electrically conductive element fits within a distal end of the electrically insulative element, and where the proximate portion of the first electrically conductive element and the proximate portion of the second electrically conductive element are located external to the electrically insulative element. The electrically conductive weights are located within a cavity of the sensor, wherein the cavity is defined by surface of the first electrically conductive element, the electrically insulative element and the second electrically conductive element.
