Regarding the information listed above, which was
the important factors for artificial incubation, an
automatic incubator was then designed. This machine
contained one tray of 30 eggs. The dimension of
incubator cabinet was 0.47×0.48×0.41 m. For the
permanent and inexpensive to operate, inside wall was
constructed of zinc sheet, whereas outside wall was an
acrylic plastic sheet. The insulation was constructed
from plywood. The heat source was four lamps of 60
Watts halogen. Water tray was placed on the bottom
floor of cabinet to increase and recover humidity in
cabinets. Thermocouple type K, was selected to
measure temperature and humidity in cabinets. An
AP104 board worked for control temperature and
humidity. Two little fans were also installed to ventilate
air inside cabinet. Limit switch was installed outside the
cabinet to manually turned eggs tray.
