Design of Voice Prompt Temperature Detection System

Article Preview

Abstract:

A kind of intelligent prompt temperature measurement system was designed which was based on single chip micocomputer. It used the pyroelectric infrared sensor to collect the emitted infrared from human body and to preprocess the signal output of the sensor.Then it could be the conversion signal by the A/D transformation inside SCM .The AVR SCM could control to realize the temperature operation and processing, and send the temperature value to the LCD to display and the voice prompt. Simultaneously, it was added the clock function and over temperature alarm function which made the design more practical. Theoretical basis and the software platform were used in this design of the hardware production and software debugging, and finally the design requirements were realized. The temperature measurement system had the advantages of short response time, non-contact,no interference by temperature field, convenient operation.
