enLink Outdoor Air Quality Sensors

The enLink Outdoor Air Quality Sensors accurately measure:

  • Temperature (°C)
  • Relative Humidity (%RH)
  • VOCs
  • Barometric Pressure
  • Particulate Matter (PM1, PM2.5, PM4 & PM10)
  • EPA AQI Air Quality Index (based on NO2 and O3)
  • CO2 (optional)

enLink Outdoor Air Quality sensor

Available in either battery or mains powered options, both variants are easily deployed making the enLink OAQ sensors a straight forward, simple way of accurately accessing your environmental and air quality data.


  • MCERTS certified particulate matter sensor provides precise measurements of PM1, PM2.5, PM4 and PM10
  • Ozone measurement down to single digit parts per billion (ppb) resolution using breakthrough self calibrating sensor arrays
  • AQI sensor detects Ozone and Nitrogen Oxides as low as 20 parts per billion (ppb) to provide an Air Quality Index (AQI) based on international standards
  • Up to 16km LoRa wireless long range
  • Battery (4 x ER14505 3.6V Lithium AA Size) or mains powered
  • LoRaWAN Class A or Class C

These sensors can either be mains powered to offer maintenance free monitoring or battery operated (with 4 x AA size 3.6V lithium batteries) enabling a complete wireless solution for your air quality monitoring.
