PMsense
Measurement of exact content op PM1.0, PM2.5 and PM10. Stand-alone or easy to integrate in Automatic Weather Station. Easy Cloud Connection.
PMsense is a PM1.0, PM2.5 and PM10 Particulate Matter transmitter with RS485 Modbus-RTU output, suitable for outdoor air quality monitoring.
The dust particles concentration is measured using the laser scattering principle.
The transmitter is maintenance-free and has fast response, high sensitivity and an excellent stability.
Description
The PM sensor can be operated in two ways:
- Continuous operating mode: the sensor is always active and measurements are continuously taken. In this mode at least 10,000 hours of PM sensor life are guaranteed.
- Discontinuous Operating mode (default): the sensor is activated at regular intervals, when measurements have to be taken. This mode increases the PM sensor life.
On request, an optional sensor can be integrated in the transmitter.
The transmitter can be supplied with up to 2 optional configurable 4,,.,20 mA, 0…5 V or 0…10 V analog outputs.

PMsenseCR -PM and CO2 Transmitter
CO2 -Air Quality
Precise measurement of Particulate Matter and CO2 for expert environments.
PMsenseCR is a PM and optionally CO2 transmitter, ideal for pharmaceutical and high-tech cleanrooms where contamination control is critical.
It ensures compliance with ISO 14644 standards using laser scattering technology to detect and classify particles by size.
Reliable & Maintenance-Free
Built for long-term stability, PMsenseCR offers fast response, high sensitivity, and extended operating life – no routine maintenance required.
Optional Sensing
Add an integrated sensor for comprehensive indoor monitoring.
Flexible Operation & Output
Choose between continuous or cyclic measurement modes to optimize sensor lifespan. Supports RS485 MODBUS-RTU/ASCII and 4…29 mA outputs, with five measurement channels:
- 1:>0.3 m
- 2:>0.5 m
- 3:>1.0 m
- 4:>2.5 m
- 5:>5.0 m
