  • Page 3 Using the latest gas sensing technology, the enLink Air-X provides excellent accuracy and extended instrument longevity. Incorporating long range LoRa™ wireless, the enLink Air-X Outdoor Air Quality Monitor can transmit data for up to 16km, seamlessly linking data to the cloud, providing visual, easy to analyse information.

  • Page 4: Introduction

    For many applications Synetica can supply enLink Air-X with the AppEUI and AppKey pre-configured, so providing the LoRa gateway has the matching values, the join process will happen automatically once the enLink Air-X unit is in wireless range and switched on.

    All parameters can be toggled on or off from the menu. The above parameters can also be set via LoRaWAN downlink message. https://github.com/synetica/enlink-decoder?tab=readme-ov-file#particulate-sensor-downlinks for more details.

  • Page 11: Co2 Sensor Auto Calibration Configuration

    CO2 Sensor Auto Calibration Configuration To view and set CO2 sensor calibration information, enter C and the screen below will show. Please see the table below for information on each menu item. Menu Item Description Details Shows the last CO 2 value read and the minimum CO 2 value read since the last auto Last/Minimum Reading calibration.
  • Page 12 The CO2 sensor needs to be exposed to fresh, clean air periodically for the auto calibration to be successful. Most occupied areas are unoccupied for some time during a week-long period, typically at night, or at the weekend and therefore the auto calibration runs every 8 days by default. Background CO2 levels are typically around 400-450 ppm, if the background CO2 level is known to be a different value then this can be set in the “Set Target CO2 Level”...

  • Page 13: Co2 Monitoring

    CO2 Monitoring Measuring CO2 levels can serve as a good indicator of the indoor air quality. CO2 concentrations within a building are often used to indicate whether adequate fresh air is being supplied to the space. Indoor CO2 concentration is directly proportional to the number of people in a building and the ability of the ventilation system to dilute the CO2 generated by occupants.

  • Page 14: Voc Monitoring

    They do not generate personalised information. The enLink Air-X unit incorporates a highly sensitive VOC sensor for air pollution measurement. Gases that can be detected by the VOC sensor include: Volatile Organic Compounds (VOC) from paints (such as formaldehyde), lacquers, paint strippers, cleaning supplies, furnishings, office equipment, glues, adhesives and alcohol.

  • Page 15: Live Menu
