    It is managed to complete v1 of the plantduino system.  It’s pretty basic, but it gets the job done:

    • PoE power support 9V fed over PoE to EtherTen Arduino board
    • Seeeduino grove system, with grove base shield, grove relay, grove serial LCD, and grove moisture sensor
    • Moisture sampling every 14,400 seconds (= 4 hours)3,600 seconds (= 1 hour)
    • If moisture threshold < 500 575 (0-1000 range), turn on pump in cistern for 5 7 seconds.
    • Smaller water container solves the problem of gravity and siphon force.

    Planned updates for v1.1. Currently the Ethernet is solely for power, however future modifications will be easy to implement.

    • Twitter support – tweet status of system – via DM command or @
    • Remote modification of moisture threshold, pumping duration.
    • Low water notification

    Plantduino v1

     

     

    he primary components used for the project are as follows:

    1. Seeeduino Grove Base Shield – makes it easy to attach sensors and other devices without using a breadboard. Makes it super easy to prototype various designs. Later iterations would be reduced to breadboards and final custom PCB design.
    2. Freetronics EtherTen – Arduino Uno compatible board with built-in ethernet, eleviating the need for a separate shield. Compact design. Supports PoE.
    3. Freetronics PoE injector – allows easy addition of power to PoE enabled devices. One wall wart to control up to 4 PoE devices – extremely useful.
    4. Grove Relay twig – connects to the Grove Base Shield to allow the Arduino to control the relay – up to 250V/10A loads.
    5. Submersible pump – this will be placed at the bottom of the water container. Pump is triggered by the Grove Relay
    6. Grove SerialLCD – used for displaying status of the system – moisture level, last watering datetime, etc.
    7. 4xAA battery holder – to contain battery needed to power the submersible pump. Current draw is higher than the Arduino can deliver but wanted to avoid a separate wall power supply for the pump. Later options include using the PoE to deliver suitable power and current.
    8. Grove Moisture Sensor – used to take soil moisture readings, and when the moisture level drops below a predetermined threshold, trigger the pump to water the plant.

    Check back to this blog soon, I anticipate having the bulk of this project working within two weeks, if not sooner – I am however waiting on a few misc parts, including an enclosure to house the electronics in, as well as some other plumbing parts.
