Efficiently monitor your indoor environments with long-lasting multi-gas microsensors

Introducing EnviCam®-3x-SMB, a revolutionary multi-gas microsensor that enables precise control of Heating, Ventilation, and Air Conditioning (HVAC) systems. Thanks to its cost-effectiveness and selectivity, owners and facility managers can easily comply with strict indoor air quality (IAQ) standards and ensure occupants’ well-being.
EnviCam-30 microsensor


There is a growing number of stricter indoor air quality regulations around the world, which demand selective and accurate measurements of the gases present in the surrounding environment.

To meet this challenge, the air quality monitoring market is seeking gas measurement solutions that are both selective and economical, while also having a long lifespan and being easy to integrate.

How EnviCam®-3x SMB helps improve indoor air quality monitoring

Long operating lifetime

Ultra-low-power consumption < 10 µW @ 1 measurement per second (per sensing element)

High autonomy > 5 years with self-calibration algorithms

Ease of integration

Small size, small amounts of external components (low BoM cost), algorithms internal or external to the device

High selectivity

With respect to the chemical compounds of interest (CO2, CO, formaldehyde, NO2,...)
