PROJECT 2 An embedded system for a simple Poultry Farm System is to be designed (Block Diagram, Schematics Diagram, Flow Chart and Arduino Sketch or Program Code). The Poultry Farm System concept is shown in the Fig.P2. CONTROL PANEL/BOX ENTRY GATE DEHUMIDIFIER VENTILATION SENSOR L4 L2 SENSOR L5 VENTILATION L3 3 SENSOR L6 ADJUSTABLE WINDOW OPENING Sensors 1, 2, and 3 are Temperature and RH sensor, used to measure the average room temperature and RH. L1, until L6 are lamps, they are connected in parallel. Figure P2: Mini semi-automatic Poultry Farm Your task is to design an embedded system to fulfill the following condition. ✓ The temperature and the humidity inside the Poultry House are maintained automatically with preset Temperature value of 25°C and relative humidity RH 80%. If the temperature is exceeded 25°C, then the window on the right side is opened (activated by servo motor) slowly. Outside fresh air flows into the poultry room until the expected room temperature and RH are achieved. If the temperature is still above 25°C, then the ventilation fan is ON (using DC Motor) and the speed is automatically increased if the temperature is still "high" until the expected temperature is achieved. The Relative Humidity is also controlled and maintained in RH-80% using the Humidifier Unit. The humidifier unit uses a mini pump, which is driven by a dc motor. If the relative humidity is less than 80%, then the mini-pump is spraying water mist. The Lamps L1, L3 and L5 are parallel and connected as Lamp Group 1. This group is served by a PUSH Button, and similarly the lamps L2, L4, and L6 are parallel and connected in second group also serve by a second push button. If the of the poultry room is still sufficient bright (monitor by a Light Dependent Resistor, LDR) then only one Lamp Group is ON (Lamp Group 1 OR Lamp Group 2). When the brightness is drop, the all-Lamps Group are turned ON.
