Infineon Technologies XENSIV™ PAS CO2 Connected Sensor Kit
Infineon Technologies XENSIV™ PAS CO2 Connected Sensor Kit (KIT_CSK_PASCO2) is a rapid prototyping platform for use cases based on the XENSIV PAS CO2 Sensor. The PAS CO2 Sensor uses photoacoustic spectroscopy (PAS) to detect the pressure change generated by CO2 molecules. CO2 concentration is then delivered in the form of a direct ppm readout thanks to the integrated microcontroller. The Sensor Kit also includes the DPS368 Barometric Pressure Sensor. The DPS368 offers high accuracy, low current consumption, and can measure pressure and temperature.The Infineon Technologies XENSIV PAS CO2 Connected Sensor Kit consists of a compact, Feather-compatible Wing Board and a Rapid IoT Connect Developer Board. The Connected Sensor Kit combines sensing with a low-power dual-core PSoC™ 62M Microcontroller and BLUETOOTH® and Wi-Fi® connectivity options within a software ecosystem provided through ModusToolbox™.
Features
- Small 22.5mm x 63.0mm x 30.0mm Feather-compatible form factor
- Interchangeable sensor Wing Boards can be stacked individually or combined
- Dual-band (2.4GHz and 5.0 GHz) Wi-Fi and Bluetooth 5.0 compliant combo radio module
