Using the SmartGarden3 Wiring Hub for your Projects
The SmartGarden3 Hydroponics unit comes with a wiring hub to connect up the power, pump and light. It turns out that this board is really handy for adding additional devices to relays on the SmartGarden3 or for other projects and your relays.
See the SmartGarden Hydroponics Kit Here.
If you are adding additional 5 – 24 VDC devices, you may want to use additional SmartGarden3 Wiring Hub Boards. This is the same board that is included in the SmartGarden3 Hydroponics Kits.
You can buy the wiring hub here for $10.
It comes with a 2Amp replaceable fuse and high quality screw down connections for wires. It also has four LED Status lights.
Channel 1 is labeled Pump on the board and Channel 2 is labeled Light on the board.
You can control two channels through this board. The steps to use this board are:
Step 1) Connect your power to the Power Inputs on the right of the board.
Step 2) Connect your device to be controlled to either Channel 2 or Channel 1 Outputs (on the top left of the board)
Step 3) Connect a SG3 relay (on the SG3 Extender Board marked Relay 5-Relay 8) to control your device.
Then program SmartGarden3 to control your device.
If you want to use your own relay board, this is still a very handy wiring hub.
There is also a 3D Print housing available here and the STL files here.
It also supports:
- A DS18B20 One Wire Temperature Sensor. 4.7K pullup resistor included. Wired to a Digital / Serial port. Can be 3.3V or 5V depending on your setup.
- 4 Port Grove I2C Expander – 3.3V or 5V with I2C Activity LED.
