Air Quality Sensor Module With SGP40 VOC Sensor And Humidity Compensated Indoor Air Monitoring
The Gravity SGP40 Air Quality Sensor is a compact indoor air quality monitoring module based on Sensirion's advanced SGP40 digital VOC sensor. Built on the proven CMOSens technology platform, the sensor integrates a complete sensing system on a single chip, including a temperature-controlled micro-hotplate and humidity-compensated VOC measurement engine. Combined with Sensirion's powerful VOC algorithm, the sensor provides reliable indoor air quality data that can be directly used to evaluate air quality without requiring complex calibration procedures.
Designed for long-term indoor monitoring applications, the SGP40 features low power consumption of only 2.6mA, a fast response time of 2 seconds, and a compact form factor for easy integration into embedded systems. The Gravity interface simplifies connections with Arduino, ESP32, Raspberry Pi, and other development platforms. The sensor is ideal for smart home devices, air purifiers, ventilation systems, kitchen hoods, HVAC equipment, and IoT-based environmental monitoring solutions.
