Description: The automatic controller for a chicken coop is designed to automatically regulate light, temperature, and humidity, thereby enhancing egg production and survival rates of chickens. This device is intended for specialized poultry households in rural areas. The circuit operates through a house automation controller, which includes a power circuit, humidity detection control circuit, light detection control circuit, and temperature detection control circuit.
The power circuit comprises a power transformer (T), a rectifier bridge (UR1), an LED (HL), a three-terminal integrated voltage regulator (IC), and a filter capacitor (C1). The humidity detection circuit includes a humidity control resistor (RS), a rectifier bridge (UR2), a potentiometer (RP1), transistors (V1, V2), diodes (VD1, VD2), resistors (R1 to R4), a capacitor (C2), and a relay (K1). The light detection control circuit is made up of a phototransistor (V3), transistors (V4, V5), resistors (R5 to R8), a potentiometer (RP2), diodes (VD3, VD4), and a relay (K2). The temperature detection control circuit consists of a thermistor (RT), resistors (R9 to R12), transistors (V6, V7), a capacitor (C4), a potentiometer (RP3), and diodes (VD5, VD6), along with a relay (K3).
The AC 220V voltage is transformed by T, generating AC voltages of 15V and 6V on windings W2 and W3, respectively. The 15V AC is rectified by UR1, regulated by the IC, and filtered by C1 to provide a stable 12V DC voltage. The 6V AC voltage is stepped down and rectified via UR2, with RP1 connected to two fixed ends. When humidity is insufficient, the high resistance of RS causes a drop in the base voltage of V1, leading to the conduction of V2 and activation of K1, which connects the humidifier to the power supply. When humidity levels reach the desired range (55% to 65% relative humidity), the resistance of RS decreases, turning off V1 and V2, thus deactivating K1 and stopping the humidifier.
In terms of light control, when sufficient light is present, the internal resistance of phototransistor V3 decreases, causing V4 and V5 to turn off, which releases K2 and turns off the fill light. Conversely, when light levels are low, the resistance of V3 increases, leading to the conduction of V4 and V5, activating K2 and illuminating the fill light. For temperature regulation, when the temperature is within the optimal range (15°C to 25°C), the resistance of thermistor RT decreases, resulting in the closure of V6 and V7, which keeps K3 deactivated and the heating device off. If the temperature drops below the desired level, the resistance of RT increases, causing V6 and V7 to conduct, which activates K3 and powers the heating system. Once the temperature reaches the specified level, V6 and V7 turn off, releasing K3 and stopping the heating device.
For component selection, resistors (R1 to R12) should be 1/4W carbon film or metal film types. The thermistor (RT) should be an MF11 type negative temperature coefficient thermistor, while the humidity sensor (RS) should be an MS01-A type humidity-sensitive resistor. Potentiometers (RP1 to RP3) are made from organic solid materials. Capacitors (C1 to C4) should be 25V aluminum electrolytic types. Diodes VD1, VD3, and VD5 are 1N4148 silicon switching diodes, while VD2, VD4, and VD6 are silicon rectifier diodes. Bridge rectifiers UR1 and UR2 are rated for 1A at 50V. Transistors V1, V4, and V6 can be 3DG6 or 59013 models, while V3 is a 3DU5 phototransistor, and V2, V5, and V7 can be 3DG12 or C8050 types. The voltage regulator IC can be an LM7812 or CW7812 model, and relays K1 to K3 should be JRX-4 type 12V DC relays. The transformer (T) should be rated for 5 to 8W with secondary voltages of 15V and 6V, and the indicator LED (HL) can be 6.3V.Coop automatic controller described in this case, capable of sheds light, temperature and humidity automatically adjusted to increase egg production rate and survival rate of c hickens.

When the humidity inside the house is not enough, the resistor RS humidity resistance is large, so that the base voltage V1 due to decrease end, V2 conduction, K1 pull its normally open contact connected to the power supply of the humidifier, humidifier humidification spray.
When the humidity inside the house to meet the requirements (relative humidity 55% ~ 65%), RS resistance becomes smaller, so that conduction V1: V2 off, K1 release, the humidifier stops working. When adequate light in the house, phototransistor V3 internal resistance becomes smaller, so that V4 and V5 off, K2 is released, fill light does not shine.
When there is insufficient light inside the house, V3 internal resistance becomes larger, so that V4 and V5 conduction, K2 pull its normally open contact connected, fill light is lit. In the house temperature suitable (15 ~ 25 ), the thermistor resistance RT smaller, V6 and V7 are closed, K3 does not pull, the heating device does not work.
If the low temperature inside the chicken coop, the RT resistance becomes larger, so that V6 and V7 conduction, K3 pull its normally open contact connected to the power supply of the heating means, to start with heating. When the temperature reaches the required temperature inside the house, V6 and V7 off, K3 release, the heating device stops working.
