ND-IFD Fruit Dendrometer
What is the ND-IFD? The ND-IFD is a fruit dendrometer that continuously measures fruit diameter from 7 to 45 mm — capturing fruit growth, daily shrink-swell cycles and harvest readiness in real time. Designed for outdoor remote monitoring, irrigation control, field monitoring, smart agriculture and scientific research applications connected to the yDoc ML-525 datalogger.

Applications
Where the ND-IFD is used
Outdoor remote monitoring
Long-term fruit growth tracking in remote orchards and field stations.
Irrigation control
Detect fruit shrinkage from water stress — trigger irrigation before yield loss.
Field monitoring
Real-time fruit-growth comparison across cultivars and management zones.
Smart agriculture & research
Fruit physiology, breeding selection and post-harvest quality research.
Integration
Powered by the yDoc ML-525 datalogger
The ND-IFD connects directly to the yDoc ML-525 datalogger. The yDoc powers the sensor, schedules measurements, stores readings locally and transmits them to the Sensor-Online platform via 4G/LTE-M, NB-IoT, LoRaWAN, satellite or Ethernet — with up to 10 years of battery life.
