Unit 7.6 Lesson 4 Goals: Complete the control system (flowchart) to control all elements of the greenhouse. Test and refine the flowchart to improve how it works. Print out work and annotate it to explain what each of the parts of the flowchart controls and anything that could be done differently to improve your work.

What is a sensor? Name as many sensors as you can Can you think of a sensor that could be used when you are controlling the greenhouse?

Making decisions Write your own decision and identify the outcomes connecting them to the decisions with Yes or No arrows.
