Decentlab GmbH Indoor Ambiance Monitor, CO₂, TVOC, Motion Sensor DL-IAM

Decentlab’s indoor ambiance monitor continuously measures carbon dioxide (CO2) concentration,
volatile organic compounds (VOC), temperature, humidity, barometric pressure, ambient light, and
motion/presence. These data allow quantifying the air quality, temperature, and illumination (ambiance)
in offices, classrooms, hospitals, stores, or malls. These data also indicate the presence of people and
how they move in a room. This allows to efficiently control heating, ventilation, air conditioning (HVAC)
and illumination corresponding to the actual situation in a specific room.

PIR motion sensor measuring activity level

Description :

Barometric pressure and temperature data are used by the CO2 sensor to compensate for temperature
and pressure variations and the elevation above sea level.

In addition, the device periodically performs an automatic calibration routine for the CO2 sensor. The
calibration routine requires no interaction by the user. The calibration period is set to 8 days by default.
Every 8 days, the device evaluates all sensor data of the last 8 days and performs a recalibration. The
recalibration is based on the assumption that the sensor has been exposed to fresh air (which is
assumed to contain 400 ppm CO2) for at least a few minutes during this period. If the device is operated
indoors, it is enough to ventilate the room with fresh air once in a while.

The user can configure the calibration period for example by the following user interface commands:

  • set param 2 192 (set calibration period to 192 hours = 8 days: recommended default)
  • set param 2 0 (disable calibration function)

Please refer to section “Device configuration” for a description of the user interfaces.
