  • Patent number: 6476620
    Abstract: An electrostatic capacity sensor includes an electrostatic capacity type detection element in which a detection electrode, a ground electrode and a charge plate interposed between the detection electrode and the ground electrode are arranged in a state that they are isolated to each other; a detection circuit for detecting changes in capacitance of the detection electrode caused by an object to be detected; and a power supply for supplying electrical power to the detection circuit. Since the electrostatic capacity sensor is provided with the charge plate between the detection electrode and the charge plate, it is possible to improve the sensitivity of the detection element, so that it is possible to increase the detection distance. In addition, the variations in the capacitance of the detection element due to the changes in the ambient conditions can be reduced.
