SparkFun Photoacoustic Spectroscopy CO2 Sensor - PASCO2V01 (Qwiic)

SparkFun Photoacoustic Spectroscopy CO2 Sensor - PASCO2V01 (Qwiic) (SEN-22956)

The SparkFun Photoacoustic Spectroscopy CO₂ Sensor features the XENSIV^™ PASCO2V01 sensor package from Infineon^©. The sensor measures highly-accurate CO₂ data in direct parts-per-million (ppm) format over I²C, UART and PWM. The PAS CO2 employs a photoacoustic spectroscopy measurement system that combines narrow-band filtered IR light and a highly sensitive microphone inside the sensing cavity to measure CO₂ concentrations from 0 to 32,000 ppm with a best accuracy of ±(30ppm + 3%) when reading between 400 ppm and 5,000 ppm. It also includes a microcontroller that converts the data into direct ppm readout over any of the three communication interfaces. The IR emitter on the PAS CO2 requires a 12V supply so the board includes a AP3012 boost regulator with a series of decoupling capacitors to output a clean 12V from the 3.3V sourced through a Qwiic connection.
