Raspberry pi, with GrovePi+ to read plant data. Data is saved to temp.csv. Takes a picture on every interval. If moisture readings are "Dry" for 3 consecutive intervals, the waterpump will activate.

Sensors: moisture, light, temperature, humidity and distance.

• Raspberry Pi 3B+
  • Adapter
  • 32GB SD Card (8GB is enough when not using camera)
• GrovePi+
  • Moisture Sensor
  • Light Sensor
  • LED Red (5mm)
  • Temperature & Humidity Sensor (DHT22)
  • Ultrasonic Ranger
  • LCD RGB Backlight
  • Mini Fan
• 3-6V Waterpump
  • Aquarium tubing
  • Watercontainer (bottle, bucket.....)
  • 2 female to female jumper wires
• Optional:
  • Heatsink for Raspberry Pi
  • Raspberry Pi Camera (Board V2 - 8MP)

1. Download and burn Raspbian to SD card.
2. Do initial Raspbian setup, make sure to setup an internet connection.
3. Update Raspbian:

$ sudo apt-get update
$ sudo apt-get upgrade
$ sudo apt-get dist-upgrade

4. Attach GrovePi+ To Raspberry Pi and run:

$ sudo curl -kL dexterindustries.com/update_grovepi | bash
$ sudo reboot

5. After reboot run:

$ sudo i2cdetect -y 1

• If the install was succesfull, you should see "04" in the output.
• See GrovePi Setup if unsuccesfull.

6. Connect waterpump to Mini Fan board:

• Carefully take off the plastic shell of both the jumperwires, on one end.
• Pull the waterpump wires through the small holes of the shells.
• Put the waterpump wires in the stripped opening of the jumperwires and attach them with some plyers
• Pull back the shells.
• Attach the other end of the jumperwires to the Mini Fan board, where the Mini Fan plug normaly goes.
• Attach aquarium tubing and put in watercontainer.

7. Connect sensors to the GrovePi ports:

Feel free to use different ports, just be sure to change them in growpi.py.

8. In your growpi directory, create a file called secrets.py.
9. Inside it fill out your ftp url, username and password:

FTP_URL = '<your_ftp_server>'
USERNAME = '<your_ftp_username>'
PASSWORD = '<your_ftp_password>'

10. Copy the contents of the website directory, to the root of your website.
11. Launch growPi:

$ python growpi.py

• Base script
• Add Sensors: Moisture, Temperature, Humidity, Light
• Add red led as indicator for low moisture
• Add display, that displays current data
• Save sensordata to csv file
• Add camera
• Add waterpump
• Write watering logic
• Write waterpump setup
• Get stable sensor data from Ultrasonic Ranger
• Make Webapp/site that auto updates with sensordata
• Add Jupyter notebook with EDA if interesting
• Should really change ledmoist.py filename

• The waterpump in this setup produces about 5ml/second. Make sure to test how much your setup produces, results may vary.
• If you don't want to use the website, just remove all uploadCSV() and UploadImage() functions from the main loop.
• If you want to get the timelapse video, download timelapse.py and secrets.py, and run timelapse.py on your local machine. Or upload them to a server and add timelapse.py to a cronjob, so the video will get updated automaticly.
