In order to make sure people can drink a variety of beverages in the normal temperature conditions in daily life. I have the design which used the effective design of temperature sensor and voice integrated circuits,producing the voice to prompts people the temperature of the liquid. This design used DS18B20 temperature sensor to measure temperature of water,using C language to program. The design used AT89S52 microcontroller to processing section of temperature data collected by DS18B20 , and it could control the audio recording broadcast circuits ISD1420 which used to choose voice to played. The LCD liquid crystal to display temperature data. ISD1420 must be used to record voice first to make the user identify the temperature, for example, when the temperature is above 70 ° C ,the system will play too hot, when the temperature is at 30 °C to 70 °C ,it will play te
