基于霍尔传感器的水位控制系统设计

The water level control system based on hall sensor design

本文以水资源的有效利用为背景,设计一个水位控制系统.使用HAL248型霍尔开关作为水位检测传感器,利用条形磁铁产生磁场,磁铁随水位上升,磁场强度达到一定值后霍尔开关打开,输出信号,通过控制电路,最后带动电机转动,达到调节水位的目的.该装置可以实现缺水时可以自动补水,水位过高后能够自动排水,可以保证水位始终保持在一个稳定的值.

based on the effective utilization of water resources as the background,design a water level control system. We use type HAL248 hall switch as the water level detection sensor. A magnetic field using the bar magnet,the magnet follow with the water level rise,hall switch after magnetic field strength reaches a certain value,and output signal,through the control circuit,and finally drive motor rotation,achieve the purpose of regulating water level. When using the device,the water can automatic filling water,high water level after automatically drainage,ensure that the water level always stay in a stable value.
