With the continuous improvement of people's living standards, the MCU control is undoubtedly one of the objectives pursued by the people, the convenience can not be negative . Temperature monitoring and control technologies are applied more extensively in various fields, it demands more and more people, to work for modern, scientific research, life, the more convenient to provide better facilities on the need to start with a few microcontroller technology, all In a digital control, intelligent control direction.
Figure thermometer design does display mainly from SM410361K liquid crystal module , the P89V51RD2 monolithic machine module assumes program control,NTC thermistor makes the sensory temperature module chip , realizes a figure measuring the temperature.
The temperature designing that the what be introduced that figure thermometer has numerical reading going to the lavatory , measures temperature range expanding, measures compared with the tradition thermometer originally, is accurate,whose output temperature adopt a digital display, is used to be put into use to measuring comparatively accurate lieu of temperature,or the scientific research laboratory mainly.
