| Abstract: | A temperature detection system based on AT89C51 is designed in the alarm system as the wide applications of MCU in instrumentation fields. That conversion from Temperature to electric signals is realized by temperature sensor AD590,and A/D is completed by AD574 and temperature display implemented by shift register 74LS164. Test results show that the system works stable and reliable with simple circuit. |
