What this sensor gives the BOM
Infineon XENSIV PASCO2V01BUMA1 is a CO2 sensor that talks three digital protocols — I²C, PWM, and UART — so the same part fits a UART-only MCU or an I²C bus without a translator IC. Runs on a single 3 V supply rail, drawing 6.1 mA typical. That supply voltage aligns with common 3.3 V systems; a 3.0 V LDO or a direct coin cell works.
Where the temperature grade puts the limit
Rated 0°C to 50°C ambient — this is a desk, conference-room, or hospital-ward sensor, not a rooftop air-handler or a factory floor unit. If your application sees sub-zero or sustained 55°C plenum air, this part will drift or shut down.
