ND-PM Particulate Matter PM1/PM2.5/PM10 Sensor
What is the ND-PM? The ND-PM is a multi-fraction particulate matter sensor measuring PM1, PM2.5, PM4 and PM10 simultaneously, plus temperature, relative humidity and barometric pressure. The optical particle counter delivers ±5 µg/m³ + 5 % accuracy on fine particles — ideal for indoor and outdoor air quality, global environmental surveillance, public buildings and HVAC control deployments connected to the yDoc ML-525 datalogger.

Applications
Where the ND-PM is used
Outdoor air quality
City-scale PM monitoring for environmental policy, citizen alerts and traffic management.
Environmental surveillance
Global air-quality networks and long-term trend analysis for regulatory compliance.
Indoor air quality
Schools, classrooms, hospitals, stores and shopping malls — occupant health monitoring.
HVAC control
Demand-driven ventilation that responds to actual particulate levels, saving energy.
Construction monitoring
Real-time dust monitoring on construction and demolition sites for compliance and worker safety.
Integration
Powered by the yDoc ML-525 datalogger
The ND-PM 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.
