The previous level of detection is done by hand, on duty around the clock monitoring of water level changes, in terms of personnel, time and money will result in great waste. Also easy to go wrong. This topic can automatically detect a water level, and according to changing conditions automatically adjust the water level automatic control system, the measured water level changes into corresponding electrical signals, or time-based console application microcontroller integrated circuits for the received signal data processing, complete the appropriate level display, control and fault alarm functions. This article describes the reservoir level the principle of automatic monitoring alarm system, the system to MCS-51 MCU 8051 series as the core control device CPU. Sensors are 1B32 pressure sensors, data acquisition part of the way multi-way switch, pressure sensor using analog data acquisition, sensor signal into a non-power electrical signals, amplified by the amplifier into an 8-bit serial ADC ADC0809 When the AT89C51 microcontroller receiving the control software instructions issued by the channel acquisition, collecting the signal into the microcontroller through the serial interface, LED digital display chip from the on-site display. Some of the major use of assembly language
