Increasingly efficient building insulation can help to mitigate the effects of climate change, but heavily insulated
buildings are not always good for human health. Poor ventilation can result in lower oxygen levels and a build-
up of carbon dioxide (CO
2
). Even moderate levels of CO
2
can have a negative impact on health and productivity.
Already at 1000 ppm, people begin to experience drowsiness and have difficulty concentrating. Consequently,
t
here is a growing demand for smart indoor air quality sensors that can “smell” rising levels of CO
2
and either
alert the user or trigger a system response. This user guide describes the required software and hardware,
including how to set up and get started with Infineon
’s
CO
2
sensor solution using the CSK. Please refer to the CSK
user manual for more details on the CSK. Additional documents are available and are listed at the end of this
document.
The board also compraises the
XENSIV™
DPS368 digital barometric pressure sensor. This high-precision pressure
sensor can detect very small changes in barometric pressure, which makes it an ideal device for use cases where
accurate pressure event detection is required (e.g., opening of doors or windows, or fall detection).
Having both the CO
2
sensor and pressure sensor on the board gives the possibility to develop and test more
complex scenarios where data from both sensors is combined for more reliable event detection.

XENSIV™ PAS CO2
Infineon’s XENSIV™ PAS CO2
sensor leverages photoacoustic spectroscopy (PAS) technology to provide an
exceptionally small, real CO
2
sensor, overcoming the challenges of existing CO
2
sensor solutions. Its
unprecedentedly small form factor in a surface-mounted device (SMD) package allows for smooth high-volume
assembly and easy system integration.
