Based on the design of MS5561 level sensor
ABSTRACT
Based on SCM and C language level sensor design, can be used for petroleum chemical industry, metallurgy, electric power, pharmacy, water supply and drainage, environmental protection. Use level sensor is a kind of effective contact measurement methods, and can be widely used in various measurements of occasion. With high precision, low power consumption, the pensation and digital correction, without ponents, moistureproof protect, pressure and temperature measurement. This level sensor using MS5561 device, including a precision piezoresistive pressure sensor and a 51 SCM. Using temperature sensors for pensation and improve the measuring precision. In the hardware circuit, and on the basis of C language of the concrete realization each functional program. In voltage support, provide a pressure and temperature of the 16 bits of data. It adopts three-phase serial munication. Exquisite structure, simple adjustment and flexible installation way for users to easily use provides convenient. This paper describes the use of sensor and single-chip puter measure temperature and pressure principle. Through the sensor chip to enter the data and single chip, and get a temperature and pressure.
