01. SENSOR
In your pot
The Sensor seamlessly plants into your pot and tracks the 4 critical factors for plant health: water, light, temperature and humidity.
Soil moisture
Never over or under water again.
%Two probes read moisture every 15 minutes. Willow factors in species, soil type and the season, pings you when it's time to water and checks in after to see if you got it right.
Light
Find the right spot. No more guesswork.
LUXTrack ambient light throughout the day and night then get suggestions in the app for better placement based on your plant’s needs.
Humidity
Say goodbye to crispy, droopy leaves.
%Monitor humidity swings and get notified when conditions drift outside your plant’s comfort range.
Temperature
Comfy conditions, year-round.
°C / °FKeep an eye on hot/cold spikes, and get recommendations to stabilize temperature around your plant.
02. HUB
In your house
Small but savvy. Plugs into a wall outlet and sends your plant's data to the app, anywhere, any time.
