automated hydroponic system ?
I want to make automated hydroponic grown plant system that will sense condition and provide sufficient Mineral Nutrients for growing hydroponic plant.
we place the seed into water, seed grow into water , growth should start after 2 or 3 weeks.we don’t feed fertilizer until the first set of true leaves appears When seeding develop their true leaves and roots. Its time to feeding fertilize.we need to provide right fertilizer for good growth
Most common fertilizer is NPK, after two or three weak or after the first set of true leaves appear we need to fertilize plant. Fertilize approx every two weeks
Automated system (small and low cost system)
Parameter – conductivity
Project part list
Amplifier or filter
A to D converter Ic
Volve or relay
Automated system that Add more or less fertilizer into water ,that maintain conductivity range
Best time to fertilize plant
Time- fertilize plant after their active growth ,after two or three weak or after the first set of true leaves apper we need to fertilize plant
ADD small value of NPK into water because small plant take less fertilizer
After two weeks Add large value of NPK into water because large plant take large fertilizer
Provide enough NPK to complete their life cycle
we can measure conductivity of whole solution.
how to make Automated system that will Add more or less fertilizer into water on basis of conductivity
If plant need more or less fertilizer system will adjust itself
