AUDIENCE: That was awesome, but my card was stolen.
[LAUGHING]
GUEST SPEAKER 1: So this is the Soil Moisture Inversion Level
Estimator, or SMILE, for short, and it
will keep your plants happy.
GUEST SPEAKER 2: By telling you when your soil is too wet, too
dry, or just right.
So it uses an RGB LED, and any soil moisture sensor.
GUEST SPEAKER 1: And here's how it works,
GUEST SPEAKER 2: So just water turns blue, and that's too wet.
GUEST SPEAKER 1: It says "Gone Fishing" in the silly monitor.
[LAUGHING]
GUEST SPEAKER 2: Moist soil will turn green
if you stick it in all the way.
And then it says--
what does it say?
GUEST SPEAKER 2: I feel good.
GUEST SPEAKER 2: I feel good, so you
don't need to water your plant.
And then completely dry soil is red, and it says--
GUEST SPEAKER 1: I'm thirsty.
GUEST SPEAKER 2: Water me, I'm thirsty.
