The purpose of this project was to build a Garden House using Arduino. Therefore the 3 students in the group decided to make an automatic Greenhouse, the automatic parts of the house will be that the data from a soil sensor, and a humidity/temperature sensor will be able to read on a Bluetooth app created from app-inventor, there will also be a water pump that automatically will start when the soil sensor gives a signal because the earth is to dry, then the pump will start up for a moment until the soil reach the right limit of humidity.
outside the house there will be a main tank for water where there is a level-sensor that makes a warning if the main tank is about to run empty.
inside the house is a lamp with a timer to grow the Vegetables / Exotic Flowers. And a ventilation that can be started if the temperature gets too high.

Step 1: Part List
The parts used for this project is:
1x Arduino Mega
1x Bread board
1x Bluetooth module
1x DHT11 Temperature & Humidity sensor module
1x Soil Moisture sensor
1x Mini nedsænkbar vandpumpe 3-5V
1x 1meter Slange til vandpumpe
1x Float Switch, væske niveau sensor, Vandret montering
4x 330 ohm resister
1x 10k ohm resister
Step 2: Setup
Since the TinkerCad Program did not have all the templates, we have used a potentiometer to illustrate our Soil Moisture. And a Switch to illistrate the Floatswitch.
Pin 8: Float switch
Pin 7: Bottom Press
Pin 13: Moisture in Soil LED if motor stopped
Pin 6: LED Motor if running
Pin 9: Indoor light
Pin 2: LED simulated ventilation
Step 3: Code
The arduino and app code for the projekt.
The projekt needs the library function https://github.com/adafruit/DHT-sensor-library for DHT11 sensor
App code for the greenhouse can be found in the word file.
Step 4: Poster
Step 5: Video
This is the video of the automatic greenhouse
Step 6: 3D Laser Cut for Greenhouse
We used autocad for the design of the greenhouse.
