基于单片机的温度采集系统设计

his article describes a temperature acquisition system. This design uses the SCM of AT89S52 as hardware core , combining with other peripheral circuits such as keyboard interface circuit,LCD display circuit,power circuit, voaltage convert circuit and voice alarm circuit.Using the flexible programming and the rich I/O port of the SCM ,the system can processing and transmission the collected data .In the software part, on how the computer receiving data were introduced . The system can in real time and viewed on a computer on the local temperature and set temperature alarm threshold.
