Greenhouse Effect

School project: Famagusta/Avgorou Regional, Agricultural, Technical and VET school

The greenhouse has:

Temperature, Relative Humidity and Soil Moisture Sensors, Window Control Mechanisms, Ventilator, Recirculation Fan, Air Heater, Humidifier, Lighting Lamps, Automatic Watering.

Mode:

The sensors give the main computer all the information and through an Arduino programmer all the mechanisms are controlled, which work harmoniously to achieve ideal conditions for the growth of the crop.

Control:

When the temperature exceeds 27 oC the window mechanism gradually opens the windows so that the temperature drops, if the temperature continues to rise and exceeds 30 oC then the windows are closed and the ventilator starts to provide dynamic ventilation. Finally, if the temperature continues to rise and exceeds 35 oC, then the cooling system sprays water into the greenhouse so that the temperature drops with evaporation.

During the day when the temperature drops below 18 oC the window is closed to increase the temperature (greenhouse effect), in the evening hours or on cloudy days the air heater is activated to increase the temperature

The reduction of the relative humidity is done by using the ventilator, while the increase is by spraying and evaporating water (humidifier – water mist).

Uniform distribution of relative humidity and temperature inside the greenhouse is achieved by using a circulation fan

In the ground there is a moisture sensor through which the electric valves are activated for automatic watering

Special lighting lamps increase the photosynthetic capacity of plants or control photoperiodism (photosynthesis and photoperiodism)

School project: Politeknika Txorierri

(ING) In this collaborative project we want to raise awareness of the consequences of the greenhouse effect on plants. To do this, we have designed several greenhouses where we have sown seeds of different plants such as beans and lettuce. After the seeds germinated, we introduced sensors inside the greenhouses to measure the temperature and humidity in-situ, so we could control the growth of the plants and know the effect of heat on the plants studied.Finally, we present a brief report and descriptive video with the steps we have followed.

(ESP) En este proyecto colaborativo queremos concienciar sobre las consecuencias del efecto invernadero en las plantas. Para ello, hemos diseñado varios invernaderos en los que hemos sembrado semillas de distintas plantas, como alubias y lechugas. Una vez germinadas las semillas, hemos introducido sensores en el interior de los invernaderos para medir la temperatura y la humedad in-situ, así hemos podido controlar el crecimiento de las plantas y conocer el efecto del calor sobre las plantas estudiadas. Finalmente, presentamos un breve informe y un vídeo descriptivo con los pasos que hemos seguido.

(EUS) Lankidetza proiektu honetan, berotegi-efektuak landareetan dituen ondorioak ezagutu nahi ditugu. Horretarako, hainbat negutegi diseinatu ditugu, eta bertan hainbat landareren haziak erein ditugu, babarrunak eta letxugak, esate baterako. Haziak ernaindu ondoren, sentsoreak sartu ditugu berotegien barruan tenperatura eta hezetasuna in situ neurtzeko. Horrela, landareen hazkundea kontrolatu ahal izan dugu eta beroak landareengan duen eragina ezagutu ahal izan dugu. Azkenik, txosten labur bat eta jarraitu ditugun urratsak deskribatzen dituen bideo bat aurkezten ditugu.

Creating a Greenhouse

Extending grow season, isolated ecosystem, greenhouse effect, greenhouse gases

 

This challenge makes the students aware of how the growing season can be artificially extended, in an isolated, controlled ecosystem for producing healthy plants, protected from harmful, extreme natural phenomena which can be connected to the problem of climate change. It is also useful for teaching the greenhouse effect, it’s role in climate change and health issues like respiratory disease from produced gases.
