How does your plant feel today?
The problem: people love plants growing in their home and office, but sometimes
they forget to water them …
Don’t let your plant get down!
Our goal :
build a device which senses the humidity level inside the pot, and alerts when it is not sufficient
Product description
Current humidity measurement
Desired humidity level
INPUT OUTPUT
O.K. or:
Problem!

Cacti and succulents- let soil dry out almost
completely
Flowering plants-Keep
moist at all times. Don’t let the soil
dry out.
Foliage plants- keep uniformly
moist but not wet. The soil may dry
out a bit.
When should the red light turn on?
Cost • Sensor : up to 5 $
