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.
