Abstract:
For solve the problems of large volume, high cost, complex operation and other issues of the current electric field detectors, a miniaturization atmospheric electric field monitor system is developed. The system uses a capacitance as a sensor sensing unit, a twophase fourwire stepper motor as a sensor detects unit, and STC12LE2052AD SCM (Single Chip Microcomputer) with a builtin A/D converter to collect data; in this way, the circuit is simplified. Combining the Bluetooth module and the data acquisition system can realize the realtime display function, and the data can be seen in the host computer. The hardware circuit includes the amplification filter circuit, A/D convert circuit, and data acquisition and processing circuit. By MATLAB simulation and C language programming, the experimental results show that the system can meet the requirements of actual measurements, with the measuring error less than 4%.
