The flowers are hard to grow at home. Forgetting to water or over-watering may cost the life of flowers. To avoid such situation, I want to design an automatic device to raise flowers.
Using solar power as energy, the system is controlled by chip and display screen tells the condition of plant. Water and nutrition is stored, when they are need, a pump will carry them to the pot. Sensitive sensor monitors the temperature and humidity of the soil.
Another design used in public flower bed.
But unfortunately, such design is hard to be implemented in senior high school and rejected by SJTU tutor. So I changed to the group doing robot arm.
