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, we decided to make datalogging on the information given by the greenhouse, via Wamp-server, node-red and Wifi module connected to the Arduino. The automatic parts of the house will be that the data from a soil sensor, and a humidity/temperature sensor, 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. This process will be able to be monitored on the Wamp-server in real time.
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.
The communication line between the Arduino and the Datalogging goes as following. Arduino – ESP8266 – node-red – Wamp-server.

Step 1: Part List
The parts used for this project is:
1x Arduino Mega
4x Bread board
1x Wifi 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
3x ohm resister
1x 12V switch
2x 2meter RJ45 stik
Step 2: Setup
flowchart over the arduino code can be seen on the picture.
Breadboard and Schematic can be found in the Arduinoboard file.
Node-red flows are made like the pictures.
The wifi-setup is a simplex-connection.
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
LiquidCrystal.h https://playground.arduino.cc/Main/LiquidCrystal/ for LCD-skærm
ESP8266WiFi.h // Wifi module
PubSubClient.h Wifi module
Wifi and arduino code for the greenhouse can be found in the word file.

Step 5: 3D Laser Cut for the Small Greenhouse
We used Autocad for the design of the small greenhouse
The main greenhouse is made of 10mm MDF wood and polycarbonate and it measures 100x52x52.
