Microcontrollers based Liquid level control system for reservoir

Abstract Modern society, Along with the Technological and economic level evolving，The importance of water resources has been gradually coming into sight。It has become an issue  electronic  design  workers  must  consider  how  to  save  water  and reasonable

water 。Especially in industrial production, there are too many places to be on the medium container level change control, making it effective to maintain high accuracy at a set value, For example, the quality of its product life and plays a vital influence in the building materials industry, the level of stability control glass furnace。 Level control generally refers to the level of a container within the reasonable control and regulation to achieve the required control requirements。When using single-chip electronic sensor signal processing, thereby outputting a  control  signal, combined with external hardware circuit, in order to achieve the desired water level detection, water level display, motor fault detection, alarm systems and processing capabilities, high and low alert water level alarm, high and low warning level treated。Display hardware circuit diagram, and the corresponding flow chart and c language program, combined with Proteus software simulation。This enables intelligent control of the water level, such a system will be living in significant savings in material and human resources, with its development value。
