Abstract:

Aimed at the character of the polarographic typed and membrane-coated DO (dissolved oxygen)sensor, the hardware and software designs of the intelligent dissolved oxygenmeter based on ADuC834 are described, and the calibration methods and the compensation of temperature, air pressure are discussed. The result shows: making use of the powerful configuration and function of the singlechip of American ADI Co., this instrument is very intelligent, and the circuit has a simple structure, good stability, tiny error and fine measurement precision.

Key words: dissolved-oxygen, ADuC834, oxygen senor, intelligent measurement
