4. 3. Automatic Irrigation System : Autonomously water flowers and plants

   Magister-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Benjamin Brandin; Kevin Jamsahar; [2022]
   Nyckelord :Mechatronics; Cart; Microcontroller; Automatic irrigation system; Moisturesensor; Mekatronik; Vagn; Microcontroller; Automatisk bevattning system; Fuktighetssensor;

   Sammanfattning : In connection with rising urbanization and more people deciding to live in cities the opportunity to cultivate plants decreases. Indoor gardening still tends to be a popular hobby. Because the flower and plants don’t get natural sunlight and water from rain, maintenance is required. LÄS MER

5. 4. Automatic irrigation system for plants

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Hanna Hermansson; Louise Lundblad; [2019]
   Nyckelord :Arduino; mechatronics; irrigation system; moisture; plant; Arduino; mekatronik; bevattningssystem; jordfuktighet; växter;

   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. LÄS MER

7. 5. The Irrigator : Autonomous watering robot for homes

   Kandidat-uppsats, KTH/Skolan för industriell teknik och management (ITM)

   Författare :Henrik Lind; Jacob Janssen; [2019]
   Nyckelord :Mechatronics; Automated Homes; Automatic Irrigation System; Microcontroller; Line Follower; Capacitive; Resistive; Moisture Sensors.; Mekatronik; Automatiserade hem; Automatiserat bevattningssystem; Mikrokontroller; Linjeföljare; Resistiv; Kapacitiv; Fuktighetssensor.;

   Sammanfattning : Inspired by the trend of automated homes, this thesis examines the possibility of designing a cheap and autonomous robot that will water plants effectively at home. Many existing solutions are cumbersome and not sufficiently effective, often due to flexibility and risk of over watering. Therefore this thesis examines a wheel based approach. LÄS MER
