Description

Infineon has leveraged its knowledge in sensors and MEMS technologies to

develop a disruptive gas sensor for CO2 sensing. The XENSIVTM PAS CO2 is a real

CO2 sensor in an exceptionally small form factor based on the photoacoustic

spectroscopy (PAS) principle.

Infineon's MEMS microphone, which is optimized for low-frequency operation,

detects the pressure change generated by CO2 molecules within the sensor

cavity. CO2 concentration is then delivered in the form of a direct ppm readout

thanks to the integrated microcontroller. Highly accurate CO2 readings are

guaranteed.

Features

• Operating range: 0 ppm to 32000 ppm

• Accuracy: ± (30 ppm +3) of reading between 400 ppm and 5000 ppm

• Lifetime: 10 years

• Operating temperature: 0-50°C

• Operating relative humidity: 0 to 85 (Non-condensing)

• Interface: I2C, UART, and PWM

• Supply voltage: 12.0 V for the emitter and 3.3 V for other components

• Average power consumption: Typically, 30 mW at 1 measurement/minute

• Package dimension: 13.8 x 14 x 7.5 mm3
