The automatic control circuit is composed of the power supply circuit, humidity detection control circuit, light detection control circuit and temperature detection control circuit, and the circuit is shown in Figure 38. Power supply circuit is composed of the power transformer T, bridge rectifier UR1, LED HL, three-terminal integrated regulator IC and filter capacitor C1. Humidity humidity detection control circuit consists of resistor RS, bridge rectifier UR2, potentiometer RP1, transistors V1, V2, diodes VD1, VD2, resistors R1 ~ R4, capacitor C2 and relay K1. Light detection control consists of the photosensitive transistor V3, transistors V4, V5, resistors R5 ~ R8, potentiometer RP2, diodes VD3, VD4, and relay K2. Temperature detection circuit is composed of the thermistor control circuit RT, resistors R9 ~ R12, transistors V6, V7, capacitor C4, potentiometer RP3, diodes VD5, VD6 and relay K3.
