New XENSIV™ PAS CO2 Shield2Go Board for Carbon Dioxide Measurement with Integrated Prototyping Concept to Test System Behavior – EEJournal

Munich, Germany – July 27, 2022 – Poor ventilation can lead to rapid buildup of CO 2. It is a threat to human well-being, as even moderate CO 2 concentrations can affect health and productivity. Effective indoor air quality monitoring systems can prevent such problems. Additionally, carbon dioxide sensing enables energy savings through demand-controlled ventilation. However, to implement these systems quickly and easily, it is important that developers test the behavior of a system in a controllable and fast way. Therefore, Infineon Technologies AG (FSE: IFX / OTCQX: IFNNY) is launching the new XENSIV™ PAS CO2 Shield2Go board, which is suitable for both air quality monitoring and demand ventilation for cost savings. of energy.

The new board is part of the Infineon Shield2Go portfolio comprising sensors, microcontrollers and security ICs that can be freely combined as part of an integrated prototyping concept. The XENSIV PAS CO2 Shield2Go board comes with a DCDC boost converter which provides the sensor with the required 12V power supply. Thus a 5 V power supply, for example via USB supplied by a microcontroller board, is sufficient and allows prototyping without the need for an external 12 V power supply.

In addition, the board is equipped with an Infineon integrated circuit and comes with an Arduino library ready to use, like all the boards in the wallet. Adapters from Shield2Go to common Arduino Uno and 40-pin Raspberry PIs prototyping form factors are also available to support a quick start. Additionally, all boards are equipped with solderless connectors, allowing designers to stack boards instead of soldering them.

Infineon’s XENSIV PAS CO2 sensor used for the board has a very small form factor. The device offers high accuracy as well as robust performance in the ppm range (±30 ppm; ±3% of reading) meeting the most stringent air quality regulations and standards. Additionally, the sensor has advanced algorithms for compensation and self-calibration. It also has UART, i 2C and PWM interfaces, as well as various configuration options for e.g. sample rate and baseline calibration.


The XENSIV™ PAS CO2 Shield2Go board can be ordered now. Software libraries and examples for Arduino as well as a generic C++ library providing a high-level API for the board are available at More information is available at
