The Gravity SGP40 Air Quality Sensor is built around Sensirion’s CMOSens® technology, which incorporates a temperature-controlled micro-hotplate and a humidity-compensated VOC sensing element on a single chip. This design ensures stable and accurate VOC (Volatile Organic Compounds) measurements, outputting a processed VOC index that directly correlates to indoor air quality levels.
Its integrated signal processing and environmental compensation eliminate the need for manual calibration, making it ideal for integration into long-term environmental monitoring systems. The sensor’s low power consumption and compact form factor allow for deployment in a variety of indoor applications, from smart home devices to industrial air quality control systems.
