Deep into the various fields, for the production and living of people brought a lot of convenience. the monitoring instrument in our country have a certain research, development, and productivity, but won the testing instrument from technology and technology in our country, from the level of industry production specialization, and other aspects, domestic water level monitoring instrument are mainly float type water level gauge, pressure sensor level meter, This design from the analysis of reservoir water level alarm (tank was used to simulate reservoir), the principle and design method of main hardware circuit and the implementation based on micro control machine STC89C52 motor run automatically as the foundation. Control system consists of A/D conversion part of the modulus conversion system, single-chip microcomputer control, digital display part, and photoelectric alarm. The circuit is simple and sensitive monitoring alarm circuit, the operation is simple, it starts working just by turning on the power supply. The system design is novel, simple, high sensiti
