ND-ZN1-001 Dendrometer T-Shape (Stem)
What is the ND-ZN1-001? The ND-ZN1-001 is a T-shape stem dendrometer for high-resolution measurement of stem diameter changes in trees, shrubs and large agricultural plants. Resolving smaller than 0.05 µm over a 20 mm range, it captures both annual growth and the diurnal shrink-swell cycles that reveal plant water status — ideal for irrigation control, smart agriculture, forestry, plantations and ecophysiology research connected to the yDoc ML-525 datalogger.

Applications
Where the ND-ZN1-001 is used
Irrigation control
Plant-based irrigation triggers using diurnal stem shrinkage as the actual water-stress indicator.
Smart agriculture
Stem growth monitoring in fruit trees, vines and high-value crops for precision management.
Forestry
Long-term tree growth and water status studies in commercial and natural forests.
Plantation research
Genotype trials, drought response studies and silvicultural research.
Ecophysiology
Plant-water-relations research for climate change, ecology and conservation studies.
Integration
Powered by the yDoc ML-525 datalogger
The ND-ZN1-001 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.
