8. The university wants to design and install smart air-conditioning (AC) controls in the classrooms so as to reduce unnecessary AC consumption and save electricity. Assume the most basic function of this automatic control is to turn the AC on only when the room temperature is high (e.g., above 26°C) and also there are people sitting inside the classroom. (a). What types of sensors are needed to construct this AC control? What are their specific functions? [6 marks] (b). Design a simple circuit with sensors for this AC control. There is NO need to take into account the precise cut-off temperature (e.g., 26°C). Briefly explain how your circuit design performs the desired automatic AC control. [6 marks]
