Build the partition walls for the hardware. The wall is approximately at 1/3 of the greenhouse. And consists of a second wall which holds the Raspberry Pi, and on the Backside the PCB.
Screw the Raspberry Bi to the wall facing the outside
Screw the LCD on the same side of the wall
Glue the light strip to the greenhouse. We started at one side of the wall going over the plants to end at the other side.
Screw the sensors to the wall facing the plants.
We put the camera on top of the wall facing the plants with 45°. We just cut the wall on the top so the PCB of the camera falls into the incision. Connect it directly to the raspberry pi.
On the other side of the wall we put the relay, buzzer and the waterpump
For the connection we used a PCB which you could also print, but it is also possible to connect all sensors and actors on a breadboard.
PCB
Get the layout and let someone print it for you TODO link layout
Solder all Connectors to the PCB
Solder the 16 pin socket for the ADC
Solder the 40 pin connector in the middle
Screw the PCB to the wall
You can now connect all Sensors and Actors to the PCB (And even more)
Digital IO connected to connectors named IO
I2C connected to connectors named I2C
Analog connected to connectors named ADC
The light strip connected to PWM
Put the ADC on its socket
Connect the PCB with the rapspberry pi with the 40 pint connector.
Breadboard
Connect the ADC to the SPI
Connect the light strip to pin 16 (PWM)
Connect the analog sensors to the ADC
Connect the I2C to the I2C pins
Connect the digital sensors and actors to the digital pins
Connect the raspberry pi with the power supply either with microusb or with a laboratory power supply on the PCB.
