本设计是基于STC89C52单片机系统控制核心的鱼缸自动换水器系统的设

This design is the design of the system to change the water tank automatic control system based microcontroller core STC89C52 using C programming language, ultrasonic level gauge detecting the liquid level, the solenoid valve controlling the opening and closing valve, the controller controls the water level, by using the liquid crystal display 1602 the display shows the parameters button control, both hardware and software, automatic intelligent control of changing the water tank. The system is automatically determined by the value of the level of ultrasonic level meter device, when reaching the set time, the pumps will start to work automatically, automatic drainage tank outwardly discharged when the water level is low, the pump stops pumping work, the solenoid valve opens automatically began to circulate water within the tank with water until it reaches the high water level to stop working.

This design is based on STC89C52 microcontroller system control core of the fish tank automatic water changer system design, using C language programming, ultrasonic level meter detection level, solenoid valve control water valve open and closed, water level controller control water level, the use of 1602 LCD display display display parameters, through key control, hardware and software, Realize intelligent control of the fish tank automatically changing water. The system is through ultrasonic level meter equipment to automatically judge the value of the level, when the set time, the pump will automatically start to work, the fish tank automatically drains outwards, when drained to low water level, the pump stops working, the solenoid valve automatically opens, the water pipe flow began to add water to the fish tank, until the high water level stops working.

This design is based on the design of automatic water changer system of fish tank based on the control core of STC89C52 single chip computer system. Using C language programming, ultrasonic liquid level meter to detect liquid level, solenoid valve to control water valve opening and closing, water level controller to control water level, using 1602 LCD display screen to display various parameters, through key control, both software and hardware, the intelligent control of automatic water changer of fish tank is realized. 。 The system automatically judges the liquid level through the ultrasonic liquid level meter. When the set time is reached, the pump will automatically start to work, and the fish tank will automatically drain water. When the water level is low, the pump will stop working, the solenoid valve will automatically open, and the water pipe will start to add water to the fish tank until the high water level is reached.<BR>
