ABSTRACT
Now, Temperature control is used in the scientific research, the production process, it’s a form of control.like many of industrial production process and beer fermentation, chemical material production, etc, in order to guarantee the safety production process, and to ensure the safety of workers and improve production under the prerequisite of the product quality and quantity, energy saving, need to make the temperature of object according to certain specified rules change.
Based on the MCS - 51 single-chip temperature control instrument is such a kind of control temperature rises, the speed and the soaking time realize strict control of temperature control meter, it is to show the temperature change, and digital control and integration, and software program temperature raising and lowering instrument .
This intelligent temperature control instrument is mainly adopts the temperature sensor DS18B20 data acquisition, relays and heating and temperature controlling transistor, LCM display the size of the temperature, of course, the core processor MCS - 51 SCM for data processing, as well as the whole system, the control system enables to control the temperature in the 20 ~ 45 °, ± 0.5 degrees.
