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 DS18B2 0 temperature sensor to measure temperature of water,using C language to program . Th e 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 to70°C ,it will play "temperature is just right" ,and ift emperature is below 30 °C ,it must be play ing "too cold" .
