| Abstract: | A multi-sensors temperature system, which constrncting sensors network by digital thermometer DS18B20 with one-wire technique, basing on serial communication is introduced. Using user-defined serial protocol, PC controls MPU to finish temperature measurement. The PC visual program interface can： add, delete, modify sensor node; add the position information for sensor node; circularly measure temperatnre for sensor nodes and alarm when it is out of range; show the temperature curve of sensor nodes etc. it has a friendly interactive interface with good effectiveness. |
