Grow plants and vegetables more aware of their environment conditions. Simply by using a MKR1000
Plant growth depends of several ideal environment conditions such as temperature, humidity, light and other mineral nutrients or oxygen.
Providing the plants with an adequate amount of water or keep the normal temperature in the green house can be a tricky process but not if you could do it it much easier.
Hardware overviewTH1 - Outside temp values will be provided from a waterproof DS18B20 sensor - D1 pin connection
TH2 - Inside temp. / hum. can be found out from DHT22 - pin D0
TH3 - FS200/SHT25 - will be introduced in soil conditions. Connections will at for SCL & SDA pins 12/11
Water leverW1 - in order to get water level will be using a ultrasound sensor like HC - SR04 Connections at A0 - Echo and Trigger at A1. Based on this value you can control a valve using R1 - 4 channels relay.
Air Temperature / OxygenA1 - Base on temperature/ humidity values you can command when to open windows using R2 relay. Based on climate you should tune it as you wish.
Relays R1 / R2To set some commands like open Windows or start any pump you could send commands to the relays ... R1 is connected to digital pins 7,8,9,10 and R2 5,6
Connections on the MKR1000
Now that we connected all things together is time to get some data and make sens using aRest library, that will provide a web interface to MKR1000 device with json format string. Use the libraries, .ino files provided bellow and change your Wifi router connection accordingly.
aRest Interface
As long that we have an interface our device we could also consume this data and see it on the local network.
We've been using Visual Studio 2015 and .net to build up a Windows application that will help you visualize green house live conditions but also a bit of daily history or all sort of logs that you want to integrate.
1 / 5 • Green House Interface
For storing in the cloud we simply used DasData green house configurations or you can create your own data channels.
DasData - channels
Next step will be to modify the DsKey and AKey provided in the Settings.txt from application folder. If everything works you should see some data online already.
Sensors in DasData channel
Follow DasData's hackster channel for more future updates
Green house AutomationYou should decide what valves or motors will create more action based on your greenhouse configuration and sizes. All this could be controlled from relays.
