Hillhead Primary School Glasgow – Years 4-6
The Heilanman’s Umbrella is an underpass that runs under Glasgow Central Station. As a major car and bus route, it traps a lot of pollutants, but homeless people still use it to shelter from the wind and rain. Our invention would monitor the levels of carbon dioxide in the underpass and, when they reach a high level, activate a fan to extract the excess and pump it into a greenhouse in Central Station. The greenhouse will create a pleasant environment for commuters with plants, fruits and vegetables growing – research shows that daily contact with nature can improve health and wellbeing.
The produce grown will also help reduce carbon footprints as people will be able to purchase the locally grown fruit and vegetables. And running the greenhouse will provide jobs for homeless people.
Using an Enviro+ sensor, we can constantly monitor temperature, humidity, light, carbon dioxide and oxygen levels within the greenhouse to maintain them at the optimal level for visitors and plants. Our system would send the data to Adafruit IO to display them as a graph on a dashboard. If the levels of carbon dioxide are too high in the greenhouse, the Raspberry Pi would switch off the fan while the plants absorb the excess.
