Abstract

• The hen egg incubator model is constructed using composite aluminum plate to enable reproduction process with the developing embryo. Light sources (40W, two bulbs) are used to maintain the require temperature. Two fans (5VDC) are also used to provide oxygen and to remove waste carbon dioxide. These are controlled by the circuit constructed using PIC16F877A microcontroller and other electronic devices. The program is written by using Basic Pro Language and it is compiled by Micro Studio Plus Software. The hexafile is downloaded by Win PIC 800. The temperature sensor, LM35DZ IC is used to detect the surrounding temperature. LCD module, TS1620L is used to display the present temperature in the hen egg incubator model from outside it. The chickens can be incubated from hen eggs by using Hen Egg Incubator Controlled Circuit.
