Generic GY-SGP40 Air Quality Sensor Module - SGP40 Metal Oxide Gas Sensor w/ I2C Interface & Header Pin
The GY-SGP40 module integrates the Sensirion SGP40 metal oxide gas sensor, providing calibrated digital air quality data via I2C. Compatible with 3.3V/5V logic systems like Arduino, Raspberry Pi, and ESP32, it delivers measurements for Total Volatile Organic Compounds (TVOCs) and an equivalent CO2 (eCO2) output for comprehensive environmental monitoring.
Features
- Sensirion SGP40 metal oxide gas sensor for TVOC and eCO2 detection.
- I2C digital interface for easy integration with microcontrollers and SBCs.
- Dual 3.3V or 5V DC supply voltage compatibility.
- Onboard 1.8V LDO regulator ensures stable sensor operation.
- Fully calibrated digital output signal simplifies application development.

The GY-SGP40 module is built around the Sensirion SGP40, a digital metal oxide (MOX) gas sensor that employs multiple sensing elements on a single chip. It provides a fully calibrated digital signal for Total Volatile Organic Compounds (TVOCs) and calculates an equivalent CO2 (eCO2) concentration, offering a robust metric for indoor air quality assessment without requiring complex calibration routines.
Designed for seamless integration, the module includes an onboard 1.8V low-dropout regulator (LDO) to power the SGP40 core, accepting a broad 3.3V to 5V DC input. The I2C communication protocol ensures reliable data transmission to host controllers like Arduino, ESP32, STM32, and Raspberry Pi, making it suitable for IoT deployments, smart HVAC systems, and portable air quality monitors.
