Temperature
Catch cold drafts and heat stress before the leaves show it.
Humidity

Water-Resistant Design
Built for home & garden.
PlantSense features water-resistant electronics sealed in the housing, and the capacitive probes carry no current through the soil so they don't corrode — making it safe for daily watering routines indoors and out. Use it on patios, in greenhouses, or beside garden beds.
While PlantSense is water-resistant and handles splashes during watering and garden use, we recommend placing the electronics housing in covered areas away from direct rain or standing water.

Sealed electronics, safe for daily watering
