What It Measures
Everything Your Plants Need
Four precision sensors in one sleek probe, paired with PlantSense Connect — designed for home & garden plant care.
Soil Moisture
Capacitive sensor tracks your plants' water levels in real time — preventing overwatering, the #1 killer of indoor and outdoor plants.
Temperature
Monitor temperatures around each plant, indoors or out. Get alerted to cold drafts, heat stress, or overnight frost before damage occurs.
Light Monitoring
Find the perfect spot for every plant, indoors or in the garden. PAR light measurements help you match light-loving and shade-tolerant species to the right location.
Humidity
Track air humidity affected by heating, AC, and seasonal changes — indoors or on the patio. Know when your tropicals need a misting or a pebble tray.
Long Battery Life
Set it and forget it. Deep-sleep cycles stretch battery life for weeks on a single USB-C charge — perfect for busy home and garden life.
PlantSense Connect
Monitor every plant from anywhere — home, garden, or on the go. Real-time readings, push alerts, and plant ID at your fingertips.
Water-Resistant Design
Built for Home & Garden Environments
PlantSense features water-resistant electronics sealed in the housing, and the capacitive probe has no exposed metal — making it completely 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.
