I am trying to build an automated hydroponic system using an Arduino board as a controller. I need the program written and the electronics built.
1. The Arduino needs to take a reading of the water tank and adjust the PPM (parts per million) by activating a relay1 that will release the nutrient solution for X ms (still need to determine how many ms are needed to be able to get a change in PPM).
2. A relay2 is activated that turns a small motor on to mix the solution for a time (time to be variable set with lcd screen)
3. Steps (1) and (2) are repeated until the PPM have reached a value: A < PPM < B
----
Once the PPM value has been reached, the Arduino reads the pH:
4. The Arduino needs to take a reading of the water tank and adjust the pH by activating relay3 that will release either an Acidic (if needed) or relay4 that will release a Base solution (if needed) for X ms (still need to determine how many ms are needed to be able to get a change in pH).
5. relay2 (same as above) is activated that controls small motor to mix the solution for a time (time to be variable set with lcd screen)
6. Steps (4) and (5) are repeated until the pH have reached a value: C < pH < D
----
Once the pH is adjusted, the Arduino loops back to the first step

i will supply rest of program once we have discussed price - program is for turning on a pump, lights, vent fan, temp up & down, also co2 on and off sensor for humidity up and down
Clionetech is expertize in all Arduino platforms' software and hardware design. We have designed several shields and custom make project based on Arduino platform. Besides coding, we can help circuit design, PCB fabrication, components sourcing and building working prototype.
