We built an improved greenhouse. We decided to optimize the environmental characteristics of a place, to improve the plant growth.
Optimize the luminosity
Optimize the humidity
Optimize the temperature
Show the different characteristics on the screen
Indicate the state of the Arduino with the RGB Led
Allow the user to change his settings with a potentiometer
All the project can run with one Arduino, but we think that it would be “cleaner” with two.
We used a solenoid controlled by a relay and a transistor, connected with a flex holed tube.
The luminosity is optimized by a servo motor, controlled by the first Arduino, which applies different angle to a Venetian store.
