XENSIV™ PAS CO2 Sensor, Efficient CO2 Measurement Based on PAS Technology

Infineon Technologies is now making full-scale efforts to respond to growing demand for sensors for CO2 concentration measurement.

Infineon announced on the 20th that it will begin mass production of the XENSIV™ PAS CO2 sensor.

This sensor is applied to applications such as △ventilation and air conditioning systems △portable indoor air quality monitoring devices △smart speakers, and enables monitoring of indoor air quality and reduction of energy costs.

Additionally, ventilation systems can be operated on-demand in classrooms, offices and other spaces, reducing operational costs.

The XENSIV™ PAS CO2 sensor won an innovation award in the 'Smart City' category at CES 2022 held in Las Vegas.

The sensor is based on photoacoustic spectroscopy (PAS) technology and enables efficient measurement with an ultra-compact size.

It is less than 1/4 the size of conventional CO2 NDIR sensors, making it the only sensor that meets California's 'Title 24 (Building Energy Efficiency Standards) regulations.

An internal microcontroller converts CO2 measurements directly to ppm output values, and these results can be utilized through serial I2C, UART, and PWM interfaces.

The CO2 measurement range is from 0ppm to 32,000ppm and the accuracy is ±30ppm ±3percent (0~8000ppm).

Infineon stated that "the XENSIV™ PAS CO2 sensor uses lead-free surface mounting with SDM-type reflow techniques and meets JEDEC international standards, which can provide greater benefits to the device manufacturing process."
