• Professional-grade VWC and pore water EC measurement for nutrient monitoring

• Substrate Moisture - Tracks volumetric water content to optimize irrigation timing and prevent crop stress

• Nutrient Monitoring - Measures pore water EC to verify fertigation delivery and detect salt buildup

• Temperature Sensor - Provides accurate air temperature readings for climate management

• Humidity Sensor - Monitors relative humidity to support VPD-driven environmental control

• Long-range LoRaWAN wireless — no WiFi infrastructure required

• Mobile and web dashboard for iOS, Android, and desktop

• Real-time alerts for threshold breaches and environmental shifts

• 1-year warranty and 90-day return policy
