SGP40 Digital Gas Sensor compatible with TVOC ECO2 GY-SGP40 Carbon Dioxide Measurement compatible withmaldehyde Module

Digital gas sensor designed compatible with easy integration into air purifiers or demand-controlled ventilation systems. Utilizes Sensirion's CMOSens® technology compatible with a complete, easy-to-use sensor system on a single chip. Features a digital I2C interface and a temperature-controlled micro hotplate compatible with enhanced percompatible withmance. Provides a humidity-compensated VOC based indoor air quality signal. The VOC Algorithm adapts to the environment, ensuring robustness against contaminating gases and long-term stability. The SGP40 is a digital gas sensor designed compatible with 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 humidity-compensated 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 compatible with 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.
