SGP40 Digital Gas Sensor Module with Cotton Core & Card Holder - 1m Cable
The SGP40 is a digital multi-pixel gas sensor module with a built-in cotton filtration core, designed for integration into air quality monitoring systems. It communicates via I2C interface and operates on a 3.3V to 5V DC supply, making it compatible with Arduino, Raspberry Pi, ESP32, and other microcontrollers for detecting a wide range of indoor volatile organic compounds (VOCs).
Features
- Digital multi-pixel MOX gas sensor for robust VOC detection
- Integrated cotton filter core protects sensor from dust and particulates
- I2C digital interface for easy microcontroller integration (Arduino, Raspberry Pi, ESP32)
- Wide operating voltage range of 3.3V to 5V DC
- Includes card holder for secure and flexible mounting

The SGP40 sensor module from Sensirion employs a sophisticated metal-oxide (MOX) sensing principle on a silicon-based micro-hotplate. This digital sensor provides a robust signal directly proportional to the concentration of volatile organic compounds (VOCs) in the air, offering excellent long-term stability and minimal drift. The built-in cotton core acts as a pre-filter, extending sensor life by trapping larger dust particles before they reach the sensitive element.
Housed in a durable black plastic shell, the module is designed for reliable operation in typical indoor environments. Its 1-meter cable provides flexibility for installation in air purifiers, smart HVAC systems, and indoor air quality monitors. The integrated card holder simplifies secure mounting within an enclosure or on a PCB.
