Sgp40 Sgp30 Air Quality Sensor Detection Chip Digital Tvoc Compatible for Arduino Demo Board

Introduction:

SGP30

The sgp30 is a multi-pixel digital gas sensor designed for easy integration into air purifiers, demand-controlled ventilation, and iot applications.®The technology offers a complete sensor system on a single chip featuring a i2c digital interface, a micro temperature controlled hot plate, and two pre-processed indoor air quality signals. As the first metal oxide gas sensor that features multiple sensing elements on one chip, the sgp30 provides more detailed air quality information.

SGP40

The sgp40 is a digital gas sensor designed for easy integration into air purifiers or demand-controlled ventilation systems. Sensirion® CMOSens technology offers a complete, easy-to-use sensor system on a single chip that features a digital i2c interface and a temperature-controlled micro heating plate, providing an indoor air quality signal from the humidity compensated voc indoors. .

The output signal can be processed directly by sensirion's powerful voc algorithm to translate the raw signal into a voc index as a robust measure for indoor air quality.

The vc algorithm automatically adapts to the environment to which the sensor is exposed. Voc's sensing element and algorithm feature unmatched robustness against contaminating gases present in real-world applications that allow for unique long-term stability as well as low traction and device-to-device variation.
