Applications of the transmitter


Specifically designed for indoor applications in an ambient environment, the Enless Wireless LoRa / LoRaWAN VOC, humidity and temperature transmitter allows you to monitor occupant comfort levels, thanks to its integrated sensors of temperature, humidity and VOC (data ppb – °C – %rH ).

The VOC content is the main indicator of the pollution and the air quality breathed by users.

VOC and air quality have a direct influence on the daily comfort of occupants in enclosed spaces, such as offices, and can trigger side effects like fatigue, drowsiness, headaches etc. Volatile organic compound particles can come from household products, paints, etc… The VOC content is measured as a percentage of air volume or as “ppb” (part per billion). Thus 1,000 ppb is equal to 0.01% of particles in the air.

Data from the sensor can be transmitted according to two radio protocols : the LoRa Enless Wireless private mode (proprietary) or the LoRaWAN mode (operated or private). To learn more about these communication protocols, see our dedicated LoRa LoRaWAN page.

Our VOC, temperature and humidity transmitter is suitable for many applications and sectors:

  • Housing
  • Public access buildings such as public educational buildings (schools, colleges, high schools, higher education establishments, training centres, etc. ), cultural (museums, castles, sports complexes, libraries, showrooms, city halls, etc. ) and sanitation (health facilities, hospitals, retirement homes, EHPAD…)
  • Tertiary sector

Our product enables compliance with government, environmental and health laws and requirements for indoor air quality monitoring (IAQ), particularly in public buildings. This monitoring IoT device contributes particularly to the monitoring of vulnerable groups such as the elderly, sick or very young.

Our LoRa / LoRaWAN transmitter can be fixed to a wall but also positioned on a surface. The frequency of sending information (periodicity) is configurable.
