Design for auto temperature alarm system based on SCM

LIU Xiang(Engineering Training Center,Wuhan University of Science and Technology,Wuhan 430070,China)  
Now it is very common to use temperature as a control volume to achieve automatic control.This paper designed a simple and practical auto temperature alarm system to meet the actual condition.This system uses SCM AT89C51 as the central processing unit,it can greatly reduce the cost of the system development.The temperature sensor LM35 is used to collect the temperature which is converted to the voltage value.AD converter converts the analog value into the digital value,then the digital value is sent to the CPU for calculation.The SCM will decide whether to start the alarm system which depended on the results of the processing.The result shows that the system is able to work under 5~150℃.When the external temperature reaches the setting value,the system can make a reply in time.So it has a certain practical value.
