Then find the relay and a Grove cable. Taking a closer look at the Grove cable you will see that one side is a 3 pin connector (this goes into the moisture sensor), while the other end is a 4 pin connector (this will be cut off in the next step, we won’t be needing that).

Now you will need to cut the Grove cable to expose the copper wire inside so you can connect it to the Nano Screw Terminal Adapter but be careful not to cut it too short at the side that goes into the moisture sensor (3 pin connector). We recommend cutting the cable close to the 4 pin connector giving you the maximum cable length. If needed you can always shorten the cable afterwards.

The USB-cable can then be plugged into any USB port, on a laptop, or in a wall-adapter, as long as it can provide at least 500 mA at 5V. Most wall-adapters meet these requirements, so don't worry too much about finding the right one.
