When working with water and nutrient solutions it is helpful to have a way to monitor the level of the liquid in its container. Additionally, it is useful to attach a flow-rate sensor to your water pump which can be used to identify issues such as a clog in the line or a disconnected water... Continue Reading →
The hydroMazing Smart Garden System does not require an Internet connection in order to grow plants. The Internet access is for you, the user and administrator of the system and any updates that I release. Data logged by the system is saved locally on the Raspberry Pi where it is processed. I designed hydroMazing Smart Garden System to grow with you as you become more advanced in your growing knowledge and techniques. The default system settings are set to grow most herbs and lettuces. These settings also include the notifications that you will receive when the system detects issues.
The Arduino Uno, and variants, should only be used for directly powering peripheral modules and not devices. Consider the maximum current consumption when determining what is a device and what is a module. A string of lights is more of a device as opposed to a panel indicator light, motor controller boards are modules, not the motors they drive, MOSFET boards, not the valves or solenoids that they control.
Electrical Conductivity or E.C. Waste Analysis Method also called ( ECWAM ) is used to determine exactly how much nutrients your plants are able to absorb.
Daily Light Integral is a way to measure how much light is available on average to plants for their absorption. Or, as described on Wikipedia, "Daily light integral (DLI) describes the number of photosynthetically active photons (individual particles of light in the 400-700 nm range) that are delivered to a specific area over a 24-hour period."
My name is Cory, I'm a Technical Craftsman specializing in creative problem solving within electronics and software engineering. Professionally, I've worked as an electronics engineer, a plastics fabricator, software engineer, an industrial laser technician, and, of course, a coffee barista. I've spent the last several years working on a Smart Garden System project I named, hydroMazing. I'm sharing my work with you because I would like to empower everyone who is interested in a "Smart" approach to gardening.
A nutrient solution system typically consists of a two or three part liquid solution containing the essential diet for a plant added to clean tap water. The manufacturer of the nutrient solution will include or reference a feeding schedule recommended for various common types of plants. Unfortunately, most minerals are mined and processed by the manufacturers, however, many offer an organic option while some specialize in only organic.
