Automatic irrigation system for plants

Sammanfattning: The purpose of this project was to develop an automatic irrigation system for plants. It is beneficial to have plants indoors. In addition to their air-purifying qualities, they have been proven to increase the productivity of employees at workplaces, as well as decrease the amount of sick leave. Three research question were investigated: how much energy the system requires and if it is possible to replace the energy source with an alternative energy source, how well the system stabilises and how a wireless regulation can be implemented. The final design consisted of a mictrocontroller which controlled the system, a water pump, a moisture level sensor and a plant on which everything was tested. The system was left during a four week period to see how well it managed. The project resulted in a system that managed to keep the plant alive. The energy demand of the system could be covered by solar cells instead of batteries.
