Electronics and Power to Create (01:35)
Electronics is about giving people the power to create and modify new environments; to see beyond conventional boundaries; to be competitive; and to produce affordable products of the right quality and quantity.
Creating Environments (02:18)
The Eden Project in Cornwall, England, focuses on the control measures needed to maintain the correct atmospheric conditions within a complex of giant greenhouses.
Humid Tropics (02:10)
The humid tropics include all the world's rainforests. In the rainforest biome, scientists work to recreate the same conditions as in the humid tropics. Sensors in two weather stations measure conditions outside the biome
Electronics and Climate Control (03:53)
Electronics continually take measurements of humidity and temperature in the biome. Data is sent to computers that are preprogrammed to respond to changing conditions by controlling a series of output devices.
Imminent Disaster? (01:43)
With the help of electronics, it is possible to dramatically reduce the impact of floods. An electronic river management system covers the entire Anglia region, a region prone to severe flooding.
Electronic Systems (02:32)
Almost any electronic system can be broken down into four key elements or stages: inputs, processing, outputs, and feedback. An electronic rain gauge feeds real-time information to the control center.
Processing: Flood Predictions (02:35)
To make predictions about potential flood conditions, the monitors rain and weather forecasts. Processing makes use of transistors, chips, and microprocessors. The central computer is linked to a series of control boxes.
Electronic System: Feedback Loop (01:53)
Through a feedback loop, an electronic system compares input from sensors with a given reference level. The system decides on action to be taken. The system controls the amount of water entering the river.
