ABSTRACT: The purpose of this paper isto explain the design of an ATmega16[1] microcontroller based egg incubator
system which is able to automatically maintain the environment which is optimum for embryo growth. The system has a
temperature sensor which is able to monitor the temperature inside and outside the incubator and this data is sent to a
microcontroller. The microcontroller, with the help of relays controls an incandescent lamp and anair circulating fan to
maintain the egg temperature from 37 to 38.5°C. In addition, an LCD display is used to display the temperature inside and
outside the incubator. The microcontroller also has a user-programmed timer to control a gear motor for tilting the eggholde
