the garden at the eco village has 3 grow beds and is a hack of the v1 controller designed for one growbed. some upgrades (code, sensors & electronics) were needed to customize this. just added another 5 sensors to this yesterday.
i have been able to call in some problems remotely for some issues to be fixed by brian at that end – mostly debris in the indexing valves (nets were put around the pumps and this has not been a problem since then).
created live graphs of the growbed sensor data and was able to catch various internal problems – (internal – means it would not really be easy to catch these the garden was not a smart garden … leave along figuring these out remotely).
the live graphs gave the first clues:
- green gb appears ok
- blue gb fills slows and drains quick … the stand pipe needs a quick adjustment(built into design) to slow the water some, the sensor needs calibration which i can do remotely by conditioning the data,
- black gb did not fill long enough … i wonder why. – the stand pipe appears is well adjusted.
just to make sure everything was working as expected i checked out the graphical simulation for this … i can see the sensors and garden relationship better with this view:
next, checked the raw arduino messages through the serial port. the json data is enriched further by by the router before transmission to remote db servers. this is shown below – notice the padded fields mapping the new garden type.
do you think you can find it in the screen below?
will fix this remotely … then will continue with the smart garden diagnosis in another blog … i suspect i still have one more problem i have not found yet probably with the garden itself.
smart garden farming is fun …
