You are asked to propose a controller design as part of a Smart Livestock Cage System. The purpose of the system is to monitor the temperature in a chicken cage and automatically turn on the cage lamp (240V) at night. The system also should turn on the cage fan (240V) when the temperature is higher than 29 °C. The controller system hardware consists of: • basic microcontroller circuit • sensors for temperature and lighting conditions. • LED for system indicator (blinking LED at a rate of 5Hz) • relay interfacing circuit to control the AC fan and lamp. (a) (b) (c) (d) From the given information, construct a detailed block diagram to plan the Smart Livestock Cage system execution. Clearly state in your block diagram the type of hardware you plan to use. Use arrows to indicate the flow of the signal. Construct a basic PIC16F877A microcontroller-based circuit schematic without the relay interfacing circuit. Draw a flowchart to illustrate the controller system execution flow based on the given requirements. Program your controller system using C language. However, the blocking delay function such as delay_ms() or delay_us() cannot be used in the system for operating LED system indicator. State all your initial assumptions about the system for your program.
