The present design is based on the number of single-chip AT89S51 thermometer in the design, used as a temperature sensor DS18B20 detection devices, at the same time can be measured 3 different locations in the temperature and the temperature alarm settings, respectively, when the temperature is not set up the framework, it could...
The design designing the figure thermometer being AT89S51 owing to monolithic machine's originally, adopt temperature sensor DS18B20 to be the detecting component , the temperature...
