I am building a hydroponic grow system, and I need to capture information and also automate the watering and nutrient dosing process as well as temperature control.
We are looking to build an automated hydroponic solution, that will be capable of doing he following:
I will also attach a diagram of the system.
1) Record water usage via flow meter, connected to the main water supply
2) Control water level in Main water tank (level censor in tank , that can open and closed solenoid
valve on main water line). Alarm via SMS when above or below a SET level
3)Measure the following values via probes in main water tank connected to the Pi
4) Measure atmospheric temperature and humidity in the grow tunnel, and display on an LCD
5) Climate control inside the grow tunnel by switching AC ON/OFF according to the desired
Automatic Nutrient Dozing System
As per point # 3, there will be 3 dozing tanks ( PH UP/PH Down/Nutrient Mix)connected to the main water tank on the system. User must be able to set the desired PH and EC value of the main water tank and according to this value the Pi must open and close solenoid valves on the Dozing Tanks PH UP/PH Down according to the reading and also for the EC value for a certain amount of seconds ( user must be able to set value in seconds), wait for a certain amount of minutes( user must be able to set value in min.) and repeat the process if needed.
6) Alarm via SMS if main water tank or sump tank pumps fail
7) Alarm via SMS when main power supply to Pi fails
