Google Apps Scripts are very powerful yet relatively unknown. In this post Fran Galarza shows us what we can do with them & IoT as a use case.

You could have a sensor regularly measuring the humidity of your garden’s soil and posting that value to your GAS (yes, you can make POST requests). Then your GAS could log that measurement in a Google Sheet and send you an email if the soil is too dry. It can even set an event in your calendar to remind you to water your garden.
