SCD40

Product Introduction

The SCD4x is a second generation optical CO2 sensor based on the photoacoustic NDIR sensing principle and patented PASens® and CMOSens® technology. It offers high accuracy at an attractive price and in a small form factor. SMD assembly allows cost- and space-effective integration of the sensor combined with maximal freedom of design. On-chip signal compensation is realized with the built-in SHT4x humidity and temperature sensor. CO2 is a key indicator for indoor air quality (IAQ), as high levels compromise human cognitive performance and well-being. The SCD4x enables smart ventilation regulation to help improve energy efficiency and human comfort. Moreover, indoor air quality monitors and other connected devices based on the SCD4x can help maintain low CO2 concentrations for a healthy, productive environment.
