Xensiv dev board tests air quality and ventilation systems
To measure carbon dioxide to ensure healthy work and living space, Infineon has introduced the Xensiv PAS CO2 Shield2Go board. It has an integrated prototyping concept to test system behaviour.
In addition to safeguarding the occupants’, carbon dioxide detection saves energy through demand-controlled ventilation. These systems can be implemented quickly and easily, said Infineon, with the Xensiv PAS CO2 Shield2Go board. The board has a DC/DC boost converter that supplies a sensor with the required 12V power supply. This ensures that a 5V supply, for instance via USB provided by a microcontroller board, is sufficient and allows prototyping without the need for an external 12V power supply.
There is also an Infineon IC on-board and the board is supplied with a ready-to-use Arduino library. Adapters from Shield2Go to the common prototyping form factors Arduino Uno and Raspberry PIs 40-pin interface are also available to support quick start up. All boards in Infineon’s Xensiv family are equipped with solderless connectors, allowing designers to stack the boards instead of soldering them.
Infineon’s Xensiv PAS CO2 sensor has a small form factor and offers high accuracy as well as robust performance in the ppm range (±30ppm; ± three per cent of reading), reported Infineon, to fulfill most stringent air quality regulations and standards. The sensor also has advanced algorithms for compensation and self-calibration. There is a selection of interfaces – UART, I2C, and PWM – as well as various configuration options for example, sampling 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 offering a high-level API for the board are available at Github.
