Closed Loop System Why Because it has feedback

(Closed Loop System) Why? Because it has feedback Input Desired result or goal of the system Compare Adjust Process Action part of the system. Involves the 7 resources of Tech Monitor Compare and Adjust Change the process to get different results PEOPLE INFORMATION MATERIALS MACHINES/TOOLS TIME ENERGY CAPITAL Used to Observe the Output Feedback Loop Used to get the Output to match the Input 7 Resources of Technology PIMTEC Output Actual Results

Systems Diagram Hydroponics PEOPLE INFORMATION MATERIALS MACHINES/TOOLS TIME ENERGY CAPITAL 7 Resources of Technology (Closed Loop System) Why? Because it has feedback Input “Grow strong healthy Compare Adjust plants in a soil free environment” Monitor: We measure the PH of the hydroponic solution and get a reading of 3. 6 Compare: Acceptable PH levels are between 5. 8 -6. 8 (3. 6 is too low and acidic) Adjust: We add a base to the solution to raise the PH between 5. 8 and 6. 8 Process “Research, Design, Build, Use and Maintain the Greenhouse” Monitor Feedback Loop Record growth levels. Adjust We monitor and collect the following data in the greenhouse: PH, Co 2 levels, light levels, temperature of air and solution, plant color, solids in the solution, light and solution timers, etc. Output “Weak yellow dying plants “

How are the 7 resources of Technology applied in the hydroponic greenhouse systems at TCMS? • PIMTEC – People : research, design, draw, build, maintain the greenhouse, people monitor and the plants and adjust settings, people collect data, people eat the plants, etc. – Information: people research on how to build a hydroponic greenhouse, different plant knowledge is needed to grow, data collection , building the greenhouse and systems etc. – Materials: materials like rockwool or other growing medium such as promix is needed, nutrients for plant growth, plastic tubs to hold nutrients, bricks and glass to build the greenhouse, etc. – Machines/Tools: tools and machines such as the pump to move the solution and irrigate the plants, the timer to turn on the pumps and lights, Nutrient salts meter to collect level of solids in the solution, hand tools such as a wrench or saw build the greenhouse and to put together the systems, etc. – Time: It takes time for a plant to germinate and grow to maturity, the timer that turns on the pumps and lights, – Energy: the potential then kinetic energy in the seed, electricity to run the lights and pump, people power to move materials , plant and harvest the crop, etc. – Capital: money to build the greenhouse, buy the seeds or other materials, money collected if you sold the crop, etc
