Introduction:

¡ñSGP30
The SGP30 is a digital multi-pixel gas sensor designed for easy integration into air purifier, demand-controlled ventilation, and IoT applications.Sensirion¡¯s CMOSens? technology offers a complete sensor system on a single chip featuring a digital I2C interface, a temperature controlled micro hotplate, and two preprocessed indoor air quality signals. As the first metal-oxide gas sensor featuring multiple sensing elements on one chip, the SGP30 provides more detailed information about the air quality.
¡ñSGP40
The SGP40 is a digital gas sensor designed for easy integration into air purifiers or demand-controlled ventilation systems. Sensirion¡¯s CMOSens? technology offers a complete, easy-to-use sensor system on a single chip featuring a digital I2C interface and a temperature-controlled micro hotplate, providing a humiditycompensated VOC based indoor air quality signal.
The output signal can be directly processed by Sensirion¡¯s powerful VOC Algorithm to translate the raw signal into a VOC Index as a robust measure for indoor air quality.
The VOC Algorithm automatically adapts to the environment the sensor is exposed to. Both sensing element and VOC Algorithm feature an unmatched robustness against contaminating gases present in real-world applications enabling a unique long-term stability as well as low drift and device-to-device variation.

¡ñSGP41

The SGP41 is Sensirion¡¯s new VOC and NOx sensor designed as digital smart switch and regulation unit for air treatment devices such as air purifiers.
?
The two sensor signals processed by Sensirion¡¯s powerful Gas Index Algorithm can be directly used to automatically trigger the removal of indoor air gas pollutants by air treatment devices without the need for user¨Cdevice interaction. This sensor solution is thus well-suited for constantly monitoring the VOC and NOx situation including potentially harmful events which are not perceived by humans. Furthermore, an automatic control of air treatment devices based on the SGP41 signals helps to save energy by turning them off once the VOC and/or NOx events have been taken care off.
