The SCD-40 is a true CO₂ sensing module that directly measures carbon dioxide concentration in ambient air using photoacoustic sensing technology. Unlike gas sensors that estimate CO₂ levels from VOC readings, this module measures actual CO₂ concentration (PPM), providing reliable and repeatable results.
This module combines two matched OPA627AU single operational amplifiers into a single dual op-amp DIP format using a precision adapter board. It is designed for upgrading or replacing standard dual op-amps in audio and analog signal applications where higher performance is required.
