To assemble the hardware, we need to correctly connect the sensor probes to the processing unit—in this case, the Intel Edison module.
Grove modules make the connections very simple, as the following steps show:
- Using the Grove universal cables:
- Attach the Grove moisture sensor to the A0 connection jack in the base shield
- Attach the Grove temperature sensor to the A3 connection jack in the base shield
- Attach the Grove relay module to the D2 connection jack in the base shield
- Attach the Grove button module to the D3 connection jack in the base shield
- Using the jumpers:
- Attach the solenoid valve's V+ end to an external 12V power supply
- Attach the external GND pin to a GND pin in the base shield
- Attach a relay connection to a GND pin
- Attach the solenoid valve GND terminal to the other relay module connection
The following diagram shows the correct connections:
