The SGP combines multiple metal-oxide sensing elements on one chip to provide more detailed air quality signals.\u003c\/p\u003e\n\u003cp\u003eThis is a gas sensor that can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. When connected to your microcontroller (running the library code) it will return a Total Volatile Organic Compound (TVOC) reading and an equivalent carbon dioxide reading (eCO2) over I2C.\u003c\/p\u003e\n\u003cp\u003eThe SGP30 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage, tracks the baseline calibration, calculates TVOC and eCO2 values, and provides an I2C interface to read from. Unlike the CCS811, this sensor does not require I2C clock stretching.\u003c\/p\u003e\n\u003cp\u003eThis part will measure \u003cstrong\u003eeCO2\u003c\/strong\u003e (equivalent calculated carbon-dioxide) concentration within a range of 400 to 60,000 parts per million (ppm), and \u003cstrong\u003eTVOC\u003c\/strong\u003e (Total Volatile Organic Compound) concentration within a range of 0 to 60,000 parts per billion (ppb).\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003ePlease note, this sensor, like all VOC\/gas sensors, has variability and to get precise measurements you will want to calibrate it against known sources!\u003c\/strong\u003e That said, for general environmental sensors, it will give you a good idea of trends and comparison. The SGP30 does have built in calibration capabilities, note that eCO2 is calculated based on H2 concentration, it is not a 'true' CO2 sensor for laboratory use.\u003c\/p\u003e\n\u003cp\u003eAnother nice element to this sensor is the ability to set humidity compensation for better accuracy. An external humidity sensor is required and then the RH% is written over I2C to the sensor, so it can better calculate the TVOC\/eCO2 values.\u003c\/p\u003e\n\u003cp\u003eNice sensor right? So Adafruit made it easy for you to get right into your next project. The surface-mount sensor is soldered onto a custom made PCB in the \u003ca href=\"\/en-eu\/collections\/stemma-qt\" target=\"_blank\"\u003eSTEMMA QT form factor\u003c\/a\u003e, making them easy to interface with. The \u003ca href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\/what-is-stemma-qt\" target=\"_blank\"\u003eSTEMMA QT connectors\u003c\/a\u003e on either side are compatible with the \u003ca href=\"\/en-eu\/collections\/qwiic\" target=\"_blank\"\u003eSparkFun Qwiic\u003c\/a\u003e I2C connectors. This allows you to make solderless connections between your development board and the SGP30 or to chain it with a wide range of other sensors and accessories using a \u003ca href=\"\/en-eu\/products\/jst-sh-cable-qwiic-stemma-qt-compatible\" target=\"_blank\"\u003ecompatible cable\u003c\/a\u003e.\u003c\/p\u003e\n\u003cp\u003eAdafruit have of course broken out all the pins to standard headers and added a 1.8V voltage regulator and level shifting so allow you to use it with either 3.3V or 5V systems such as the Raspberry Pi, or Metro M4 or Arduino Uno.\u003c\/p\u003e\n\u003ch2\u003eTECHNICAL DETAILS\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eRevision History:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eAs of October 2022\u003c\/strong\u003e – Adafruit have updated this PCB with \u003ca href=\"https:\/\/github.com\/adafruit\/Adafruit_Pinguin\" target=\"_blank\" rel=\"noopener noreferrer\"\u003eAdafruit Pinguin\u003c\/a\u003e to make a lovely and legible silkscreen - you may get the new PCB or the older version with vector fonts - both are identical other than the fancy silkscreen.
