Based on the dynamic capacitance measurement principle, an electric field measuring instrument using a miniature vibrating capacitive sensor as the probe was designed. With the miniature three-dimensional probe, this electric field measuring instrument can get induced charge from the ambient electric field at a point in a three-dimensional direction. It also has a variety of signal processing methods to improve the response of the signal by setting off analog circuits, digital circuits, and a single-chip digital smoothing filter operation. This electric field instrument can be used under extreme and large scale atmospheric environments to measure the electric field, with features such as multi-point sampling, high-frequency sampling, and high performance of anti-jamming.
