Hi there,
This is Bogdan from Romania. I'm a mechanical engineer specialized in the industrial robotic field, 3d designer and modeler.
I could design your device, which to have all the functionalities you required, but I have to tell you the methods used for such complex task are hard to harmonize. Is necessary to have several measuring systems/devices as follow:
- humidity
- pH meter
- nitrites concentration meter
- oxygen meter
- temperature
Beside all the measuring systems, is required a unifying central unit which to get all the parameters and to record or send to a reader which to have a database with different scenarios (this is another job - to create that database and the relation between the measurements and the vegetable types).
What could be done more, is to have another controller which to condition the irrigation system, the thermostat (if is intended to be used into greenhouses), nutrients, etc.
Based on your input (sketches/drawings/indications, etc) I'll make the first model of the system.
On this model, with your assistance, I'll make the modifications/adjustments/changes required until the desired system will be as expected.
When the final model is approved, I'll send you what's necessary to complete the project.
