Description

The SGP30 is a digital multi-pixel metal-oxide gas sensor designed for straightforward integration into air quality monitoring systems. Sensirion’s CMOSens® technology integrates a complete sensor system—including signal conditioning, ADC, and an I2C interface—onto a single chip. The onboard temperature-controlled micro-hotplate ensures consistent sensor performance and rapid response to changes in VOC concentrations.

This breakout board from Pimoroni makes the tiny DFN-packaged sensor easy to use on a breadboard or PCB, providing access to the I2C pins and necessary pull-up resistors. The sensor delivers two preprocessed air quality signals: TVOC (Total Volatile Organic Compounds) and CO2 equivalent (eCO2), providing detailed insight into indoor environmental conditions without requiring complex calibration routines.

Key Features

  • Dual Output Signals: Provides both TVOC concentration (ppb) and calculated CO2 equivalent (ppm) values via I2C.
  • CMOSens® Technology: Single-chip system with integrated digital processing for excellent signal integrity.
  • Optimized Long-Term Stability: Advanced algorithm and multi-pixel design minimize drift for sustained accuracy.
  • Surface-Mount Ready: Tape-and-reel packaging and reflow solderability enable high-volume, automated assembly.
  • Compact Form Factor: The ultra-small sensor footprint allows integration into space-limited IoT devices and portable monitors.
  • Robust Performance: Engineered for resilience against contaminating gases common in real-world indoor environments.

Applications

  • Demand-controlled ventilation (DCV) systems in smart buildings.
  • Indoor air quality monitors and IoT environmental sensing nodes.
  • Air purifier and HVAC system control feedback.
  • Portable wellness and health tracking devices.
  • Embedded sensing for smart home automation platforms.

Frequently Asked Questions

What is the operating voltage for the SGP30 sensor on this breakout board?

The SGP30 sensor core itself operates at 1.8V. The Pimoroni breakout board includes a voltage regulator, allowing you to power the entire module from a common 3.3V or 5V microcontroller supply. Always connect the breakout's VIN pin to your system's 3.3V or 5V rail, not 1.8V directly.

What do the TVOC and eCO2 output signals represent?

The SGP30 provides two digital outputs via I2C. TVOC (Total Volatile Organic Compounds) reports the concentration of a wide range of organic vapors in parts-per-billion (ppb). The eCO2 (equivalent CO2) signal is a calculated value in ppm that estimates the CO2 concentration based on the detected VOC levels, useful for assessing indoor air freshness without a dedicated NDIR CO2 sensor.

Does the SGP30 require calibration or a burn-in period?

The SGP30 features an integrated baseline auto-calibration algorithm that runs automatically during operation. For optimal accuracy, it is recommended to allow a 12-hour initial burn-in period with the sensor exposed to fresh air. The onboard algorithm continuously compensates for long-term drift, ensuring stable readings over the sensor's lifetime.

What is the I2C address and communication speed for this sensor?

The SGP30 has a fixed 7-bit I2C address of 0x58. It supports the I2C Fast Mode standard with a clock frequency (SCL) of up to 400 kHz. The breakout includes onboard pull-up resistors for the SDA and SCL lines, simplifying connection to microcontrollers like Arduino, Raspberry Pi, or ESP32.
