What is APEX?

APEX is a smart (not to mention cute) plant monitoring device. Just plug it into any plant and it will display the “happiness” level of the plant! This is a great reminder to water your plants if you have a bad habit of forgetting to water them.

How does it work?

Magic. Just kidding! APEX uses an Arduino attached to a moisture sensor, which is inserted into the soil of the plant. This sensor will read the moisture content of the soil, and then the Arduino calculates what face to display.

But why?

Why not?”
