ND-GMM Greenhouse Multi-Parameter Monitor
What is the ND-GMM? The ND-GMM is a 5-in-1 greenhouse multi-parameter monitor combining photosynthetically active radiation (PAR), temperature, relative humidity, CO₂ and barometric pressure in one wall-mountable device. Designed for controlled-environment agriculture (CEA), smart agriculture, greenhouses, grow rooms, vertical farming and indoor agriculture deployments connected to the yDoc ML-525 datalogger.

Applications
Where the ND-GMM is used
Controlled-environment agriculture
Comprehensive climate monitoring for CEA decision support and quality control.
Smart agriculture
Greenhouse climate optimisation for yield, energy efficiency and product quality.
Greenhouses & grow rooms
Real-time PAR, T/RH and CO₂ to drive lighting, ventilation and CO₂ dosing.
Vertical & indoor farming
Integrated climate sensing for stacked, soil-less and indoor cropping systems.
Integration
Powered by the yDoc ML-525 datalogger
The ND-GMM 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.
