The SparkFun Photoacoustic Spectroscopy CO2 Sensor features the XENSIV™ PAS CO2 sensor package from Infineon© which 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.
