AirLab, the All-in-one Indoor Air Quality Laboratory

The “Air Lab” all-in-one sensor is a total solution for measuring the indoor air  quality and environment. The sensor is used widely in schools, hospitals and office buildings for demand ventilation and general air quality measurement.

There are many sensor elements in the “Air Lab” but the main attraction is the air particle  sensor which can measure both the number of air particles and their density in several bin sizes. Supporting sensors include a C02 sensor, temperature, humidity, occupancy sensor, and TVOC sensor….  pretty much all the parameters you could ask for. The AirLab gives you confidence your building occupants are comfortable and breathing clean air.

The sensor integrates well with existing building automation systems or can operate stand alone as a general air quality monitor. Wireless communications over Wifi is supported using Bacnet IP or Modbus TCP protocols. The sensor also supports wired communications over RS485 twisted pair using BACnet MSTP or Modbus RTU protocols.


Product Highlights:

  • Particle Sensor uses the laser scatter method to accurately measure both particle density and count in five bin sizes from 0.3um to 10um.
  • Dust sensor has a long life fan rated for > 10 years maintenance free
  • Fast Response : response time less than 10 seconds.
  • Color LCD display shows air quality index and other parameters, configurable.
  •  Supports ModBus TCP/IP & BACnet IP protocol over WIFI.
  •  Supports ModBus RTU & BACnet MSTP protocol over RS485
  • TVOC sensor can detect Glycerin (Vape smoke).
  • The SPS30 dust sensor in the AirLab is MCERTS certified to DIN EN 15267 air quality standard.
  • High resolution: Particle Sensor detects both weight and count of particles in five bin sizes: 0.5, 1.0, 2.5, 4 and 10 um
  • Air Quality Index for USA, China and custom user adjusted tables are built in.
  • RS485 Baudrate:9600,19200,38400,57600,115200,76800

The Airlab sensor is an all in one solution for monitoring the indoor air quality and many other parameters of the indoor environment. They are widely used in commercial buildings, airport, and schools.

The well documented BACnet MS/TP and Modbus RTU cmmunications make it easy for system integrators to connect into existing building automation systems. The device has RS485 by default which can be configured to communicate using Bacnet MSTP or Modbus RTU protocols. There is also the Airlab Wifi model which supports communication over the Wifi lan using both Bacnet IP or Modbus IP protocols.
