Applications
Where the ND-IAM is used
Building automation
Real-time IAQ + occupancy data drives demand-controlled HVAC, lighting and access systems.
Visitor frequency
Anonymous activity and occupancy patterns for retail analytics and space planning.
Energy & HVAC optimisation
Reduce ventilation when spaces are empty — measurable energy savings without sacrificing comfort.
Workplace comfort
IAQ monitoring in shops, offices and meeting rooms enhances employee and customer experience.
Integration
Powered by the yDoc ML-525 datalogger
The ND-IAM 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.
