The automatic hydroponics system with myDAQ

The result : The result of the automatic hydroponics system with myDAQ by transform the solution concentrate of fertilizer solution and test working control quantity of wa-ter and fertilizer by using EC sensor as the table:

Conclusion and discussion 1.Get new innovation of the automatic hydroponics

system with myDAQ.

2.Get the automatic hydroponics system with myDAQ efficiently.

3.Be able to take the automatic hydroponics system with myDAQ apply in teaching activity.

Experiment The result of observing

EC value

Step 1

Testing EC value at 0.5 by us-ing buffer solution

at 0.35

Water pump doesn’t work but fertilizer solution pump work until EC value is 0.5, the system will stop working.

0.5

Step 2

Testing EC value at 0.25 by using buffer solution

at 0.35

Water pump works, fertilizer solution pump doesn’t work until EC value is 0.25, the system will stop working.

0.25

Step 3

Testing EC value at 0.35 by using buffer solution

at 0.35

Water pump and fer-tilizer solution pump don’t work until EC value is

0.35, the system will stop working.

Disaster from Flooding in lately 2011 in Thailand caused many damages in hu-man life especially products on agricul-ture. Because of Flooding for a long time we need to keep up with flooding and adjust to situation that will happen in the future. Hydroponics can control factors which effect to plant growing. As a result, we get good quality of product. The procedure produces need proficiency to look after. By the way ,we take myDAQ to apply to developed the automatic hydro-ponics system with myDAQ. It ‘s very useful to agriculturists and to adjust to flood condition taking for long time.
