IoT Hydroponics - Using Adafruit IO for EC, PH and Temperature Logging
Monitor EC, pH, and temperature of a hydroponics setup and upload the data to Adafruit's IO service.
Visit this projects Instructable's page for the full details on putting this project together.
As a quick overview, this project uses two uFire water quality sensors, the EC-Salinity board, and the ISE board to measure the conductivity and pH of a nutrient solution. It also measures the temperature.
It uploads the data to Adafruit's IO service. Their service also allows you to create a dashboard to view your data.
