Infineon Launches New XENSIV PAS CO2 Shield2Go Assessment Board

     Poor ventilation will lead to rapid accumulation of carbon dioxide. Excessive carbon dioxide concentration will affect health and productivity, which is a threat to human health. An efficient indoor air quality monitoring system can prevent such problems. In addition, based on carbon dioxide monitoring, energy can be saved by controlling the ventilation system on demand. In order to implement these systems quickly and easily, developers must test the systems in a controllable and time-saving manner. To this end, Infineon Technology Co., Ltd. has launched a new XENSIV PAS CO2 Shield2Go assessment panel, which is applicable to air quality monitoring and on-demand control of ventilation, thus helping to achieve energy conservation.

     This new evaluation board is part of Infineon's Shield2Go product portfolio. The product portfolio covers sensors, microcontrollers and security ICs, which can be freely combined as part of integrated prototyping. The XENSIVTM PAS CO2 Shield2Go evaluation board is equipped with a DCDC boost converter, which can provide the required 12V power supply for the sensor. Therefore, only a 5V power supply (for example, through the USB interface on the microcontroller board) is sufficient, and prototype design can be achieved without external 12V power supply.

     In addition, this evaluation board is equipped with Infineon IC, and like all boards in the product portfolio, it has an Arduino library that can be used at any time. It can also connect Shield2Go with the common prototype dimensions Arduino Uno and Raspberry PIs 40 pin interfaces through adapters, so as to achieve rapid startup. All plates are equipped with solderless connectors so that the designer can directly stack without welding.

     The size of Infineon XENSIVTM PAS CO2 sensor on this evaluation board is very small. The device has high accuracy and powerful performance (± 30ppm; ± 3% reading) in the ppm range, and complies with the most stringent air quality regulations and standards. The sensor also has advanced compensation and self calibration algorithms, UART, I2C and PWM interfaces, sampling rate, baseline correction and other configuration options.
