Sensors Control Systems with Flowol

Learning Objectives Identify common types of sensors used in control systems Use decision symbols in a flowchart Develop a control solution for a system that uses multiple sensors

What could you use a computer to control in your home?

Home Automation

Sensors What are these sensors? What are the inputs? What are the outputs?

The Decision symbol This symbol is used when a question must be asked to decide what to do next Decision symbols have one YES and one NO arrow going out of them to show what must happen next, depending on the answer to the question Is there smoke? Start Turn alarm on Turn alarm off Yes No

Home Automation Control Tasks: 1 Turn the living room fan on when the temperature is above 23°C 2 Turn the living room fire on when the temperature is below 17°C 3 Turn the living room lamp on when the light level is below 20 4 Ring the doorbell when the door switch is pressed 5 Turn the security light on when the light level is below 30 and the garage door sensor is on (detects movement) 6 Open the garage door when the entry button is pressed and close it when the close button is pressed
