The pet industry come into peoples lives and becomes a living, recreation and a new way of emotional sustenance in the city. It is becoming a big problem that the pet’s care can’t be meet when the owner of it is out to travel or work. The design I want to study is a pet feeder that based on a microcontroller, which is to make the feeding achieve timing, temperature measurement and voice broadcast. In this system, we use microcontroller as the core control. We use SCM STC89C52 to read the real-time clock chip DS1302 to determine the current time, The current room temperature is measured by a temperature sensor. The current time and temperature Is displayed by LCD1602 LCD. Users can modify real time and feeding time by control buttons. Key module contains four buttons, button one is used to modify real-time, button two is used to increase time value, button three is used to decrease time value and button four is used to set feeding time. After setting the feeding time, the microcontroller constantly compares the current time and feeding time during each operation period. When feeding time arrives, recording voice module controlled by microprocessor works to call the pet while motor module serves food.
