Pi Based Controller For My Indoor Greenhouse

I decided to use my Pi Zero W to control my for the moment not existing indoor greenhouse 🙂

I used all the parts laying around an it looks not so bad.

The parts I used until now:

• a Pi Zero W
• a  board with 8 relays
• a temperature sensor DHT 11
• a dc-dc converter
• and a small board with 4 transistors to use as input for the Pi
