CO2 sensor is less susceptible to interference
The XENSIV PAS CO2 sensor uses the principle of photoacoustic spectroscopy (PAS), which enables a significant reduction in form factor and a lower purchase price.
PAS, in contrast to the established NDIR technology, dispenses with a large number of optical components, and the sensor's susceptibility to interference is reduced.
The combination of a small formfactor (13.8 x 14 x 7.5 mm) and SMD technology enables easier integration into volume applications.
The XENSIV PAS CO2 is suited for use in demand-controlled ventilation systems, air conditioning and air purifiers, indoor air quality monitors, CO2 ventilation alarms and emission controls, and IoT / smart home / smart city management. The Infineon range is available at www.rutronik24.com.
Using advanced compensation and self-calibration algorithms, the sensor has a durable and consistently high measurement quality.
The accuracy for measurements in a range from 0 to 10,000 ppm (specified) is ±30 ppm or ±3 percent of the measured value.
The XENSIV PAS CO2 Sensor2Go Evaluation Kit and the Xensiv PAS CO2 Mini Evaluation Board are two development components provided by Infineon.
The Sensor2Go evaluation kit impresses with simple plug&play via micro-USB cable, whereas the Mini Evaluation Board is a low-cost way to integrate the sensor on development boards using a standard pin header.
