Next take a look at the graph in the Channels section, as shown in Figure  12-33. Your
sensor data will start populating a graph over a period of time.

Finally, ensure that your Xively trigger sends out an e-mail alert:

• If you were testing the moisture sensor using water, then take the
  sensor out. The reading should immediately go up, indicating that
  the moisture levels have dropped. Your Xively trigger will fire and
  Zapier will send out an e-mail alert.


• Similarly, if you are testing the moisture sensor using actual soil,
  take your sensor out of the wet soil. This will result in an e-mail
  alert as well.

Figure  12-34 shows an e-mail alert generated by Xively/Zapier.
