Research on Temperature Alarm Based on STC Microcontroller
The temperature alarm is to detect the outside temperature in real time through the temperature sen-sor.When the temperature reaches the set temperature value,the temperature alarm makes a sound to realize the temperature alarm.This design is an automatic temperature alarm realized by single-chip microcomputer.The 89C52 single-chip microcomputer of STC company in the United States is used;the temperature measurement uses DS18B20 digital temperature sensor,the display temperature module uses a digital tube and the alarm device uses a buzzer.Finally,it achieves the functions of temperature collection,display and alarm,and realizes the tempera-ture alarm device controlled by single chip computer.
