BalkonController

Overview

• Project-Page: https://github.com/euphi/BalkonController
• Features:
  • Controller to supply water to 4 different plant beds
  • Measurement of Temperature and Air Pressure
  • 2xRBG-Dimmer
  • LED-Dimmer (white)

Description

This device is installed at the balkony and can control a water pump and a 4xvalve to distribute water to our plants. A BMP180 sensors provides information about temperature and air pressure on I2C and is located in a seperate case in a shady place above the water tanks. Future improvement is to support an additional valve and reed contacts to automatically fill the water tanks when necessary.
