The eggs hatching incubator circuit is composed of the power supply circuit and temperature control circuit, and it is shown in Figure 4-5. Power supply circuit consists of the power transformer T, rectifier diodes VDl-VM, filter capacitor C and zener diode VS. Temperature control circuit consists of the resistors Rl-R5, potentiometer RP, diode VD5, temperature sensor integrated circuit IC, transistor V, Relay K and electric heater EH. Rl-R5 select the 1/4W metal film resistors or carbon film resistors. RP uses the small synthetic membrane potentiometer or multi-turn potentiometer. VDl-VD5 choose 1N4007 silicon rectifier diodes.
