This is a perfect project kit for advanced kids with some help from the adults and for adults trying to learn some new things. We have done this before with our successful OurWeather kickstarter so we know what we are talking about. People all over the world have built the OurWeather weather station with great success.
Smart Garden System (or SGS for short) is an introductory, easy to build Raspberry Pi based environmental monitoring and plant watering system using advanced sensors to monitor the soil moisture, monitor the sunlight, watch the air quality and monitor temperature and humidity.
It is designed to be easily and simply put together and tested with No Soldering Required!
And you get all the source code for the Smart Garden System software so you can do what you want. Modify the code to your own application! Add sensors! Add functions! Add more plants!
Please go to the Product Support Forum for the Smart Garden System on www.switchdoc.com for comments and questions.

The SmartGardenSystem is an introductory, easy to build Raspberry Pi based environmental monitoring and plant watering system using advanced sensors to monitor the soil moisture, monitor the sunlight, watch the air quality and monitor temperature and humidity. It is designed to be easily and simply put together and tested with No Soldering Required!
The base Smart Garden System supports one plant. You can add additional plants using the SGS Extender Packs.
We are using Blynk for controlling and displaying the SGS system. Here are a couple of screenshots.
We have this working right now in the laboratory.
It's pretty cool to be able to ask your Smart Garden System how it is doing!
While we will be publishing a tutorial on how to connect your Smart Garden System up to your own Alexa skill, it is a pretty complicated process for a beginner.
However, we will release a general Alexa skill that will allow you to connect up to your Smart Garden System in a very easy fashion, with little technical work.
That will be the real magic!
Our beloved (most of the time) CTO, Dr. John Shovic, always insists on putting in something about the theory behind the project. Here are his thoughts.
This was a great project to design and build. It was really an interesting process learning about the sensors, how to interconnect them and then learning about flow meters, USB Pumps and especially the software bringing them all together.
Where is the science and engineering in this project? All through it from the bottom to the top. I could go through the entire system, but that will have to wait. The most interesting points? One, we are using feedback in the system. Negative feedback to be exact. We aren't just watering on a timer, we are looking at the soil moisture and if it is high enough, we don't water. We don't water unless we need to. Very cool.
Secondly, the sensors we have in this project are amazing. For example, the Air Quality sensor is very, very sensitive. We can detect hairspray from 50 feet away (more on that in an update).
Thirdly, I got a lot out of learning how to display the data from Smart Garden on the Blynk IOT App for Android and iPhones and I had a lot of fun designing the Alexa app, although they made me take out all the cool statements. Such as asking Smart Garden "who is the coolest person you know?". The answer to that was obvious to me, but since it was debatable, we removed it. :(
