Using hydroMazing


Setup and Use hydroMazing

  • The Controller ( Arduino Nano ) uses 433MHz Transmitter to send codes to remote-controlled AC Outlets or can connect directly via a transistor, MOSFET, or relay.
  • Web Services Module ( Raspberry Pi ).
    • Optional Web-Camera ( USB Web-Camera ).
  • Optional The Advanced Controller ( Arduino Nano can connect directly via a transistor, MOSFET, or relay.  Supports additional sensors: E.C., pH, Light Intensity, more floats and flow-rate sensors.
  • Optional Zone/Node Controller(s) ( Arduino Pro-Mini with nRF24L01 connects directly via a transistor, MOSFET, or relay.  These units are solar-powered with a battery backup. Also, supports additional soil-moisture sensors.
  • Optional The Monitor (Arduino Nano ) connected to an Arduino Uno with LCD w/ Buttons Shield.

Plug-in appliances to their corresponding remote controlled AC switch units.  Most growing environments can be configured as follows:

  1. Intake Ventilation Fan
  2. Exhaust Ventilation Fan
  3. Humidifier / Other
  4. Heater / Additional Lighting
  5. Pump(s)
  • Place the hydroMazing Controller Unit inside the growing area.
  • Position the camera so that it can capture good pictures of the growing area.
  • Connect the USB cord to the Raspberry Pi.
  • Connect the power adapter to the Raspberry Pi.


I liked the simple inventory management system application so much, I borrowed it’s web interface to improve hydroMazing:
