水位传感器专用频率计的设计

DESIGN FOR A FREQUENCY METER FOR WATER LEVEL SENSOR

介绍了一种以单片机为核心构成的水位传感器专用频率计．该频率计直接用单片机的计数器对水位传感器的频率脉冲计数，从而实现频率的检测．该频率计具有结构简单、价格低、精度高等特点．

A frequency meter for water level sensor based on a single chip computer is introduced.The pulse of the water level sensor is counted by counter of the single chip computer,so its features are simple constructure,lower cost and hight accuracy.
