The output signal can be directly processed by powerful gas index algorithm in a limited space. advanced production process ensures high repeatability and reliability when converting raw signals into VOC indices as a robust measure of indoor air quality. The SGP40 is a digital gas sensor designed for easy integration of and gas index algorithms. to contamination present in real-world applications, CMOSens technology provides a complete, gas-free sensor system, enabling long-term stability and low drift and device-to-device variation. The very small 2.44x2.44 digital interface and temperature-controlled micro-hotplate provide a humidity-compensated VOC-based indoor air quality signal. Product model:SGP40, Manufacturer: Akfldms
