Product description

This Sparkfun CO2 Humidity and Temperature Sensor features the next-generation SCD40 photoacoustic CO2 sensor for high-accuracy environmental readings. The SCD40 uses Sensirion's PASens® photoacoustic measurement system that combines narrow-band IR light and a microphone inside the sensing package capable of detecting concentrations from 0 to 40000 ppm with high accuracy over 400-2000 ppm ±(50 ppm+5%). The SCD40 has an integrated temperature and humidity CMos® sensor to improve accuracy.

The SCD40 includes an automatic self-calibration routine to automatically adjust to its sensing environment over a seven-day calibration period. 

Sparkfun has written an Arduino library to make reading the CO2, humidity, and temperature very easy.
