"基于单片机的水塔水位自动控制系统设计与实现"

Water tower is a crucial component in daily life and industrial applications for water storage. The water level control system based on single-chip microcontroller ensures that the water level in the water tower is automatically maintained at a certain position to meet the water supply needs. This system uses a water level sensor to detect the water level in the tower, and transmits the signal to the STC89C52 single-chip microcontroller for processing. By adjusting the timing of the timer to increase or decrease the duty cycle, and writing the control program in C language, the system achieves motor speed control. Finally, the system utilizes an LCD1602 liquid crystal display with a character library to show the current water level status and motor speed. The system includes features such as low water level buzzer alarm, automatic handling of low water level warning, normal water level buzzer alarm, automatic handling of normal water level, and manual adjustment of PWM (Pulse Width Modulation) motor speed using push buttons. This system is adaptable to various water consumption rates in different scenarios, saving time and improving overall efficiency by automating water tower level control.
