Eggs automatic incubator 2
The eggs automatic incubator circuit is composed of the power supply circuit, temperature control circuit, temperature detection control circuit and egg timing turning circuit, and it is shown in Figure 4-2. Power supply circuit consists of the power switch S, power light HLl, power transformer T, bridge rectifier UR, filter capacitors C7-ClO and three-terminal voltage regulator integrated circuit IC2. Temperature detection control circuit consists of the resistors Rl-R6, capacitors Cl-C4, transistors Vl, V2, thermistor RT, thyristor VTl, heating lamp HL2 and heater EH. Vl uses 59013 or C8050, 3DG9013 silicon NPN transistor.
