In this chapter, we will integrate an automation twist into gardening. Using a soil humidity sensor and a relay with a pump, we will set the water pump to water the plant whenever the humidity of the soil or the garden gets low.
Here is a brief summary of what we will do in this chapter:
We will use a simple soil humidity sensor to measure the humidity of the soil or your garden
We will set a trigger for the pump to water the plant if the humidity dips to a certain level
We will connect everything to the Cloud to be monitored remotely
