The SGP40 Air Quality sensor adopts the new SGP40 digital VOC sensor chip launched by the well-known Sensirion. Based on the Sensirion’s CMOSens® technology, the SGP40 offers a complete sensor system on a single chip, a temperature-controlled micro-hotplate and a humidity-compensated indoor air quality signal. In combination with Sensirion’s powerful VOC algorithm, the sensor signal can be directly used to evaluate indoor air quality. It features low power(2.6mA), and fast response(2s). The data from the sensor can be directly used to evaluate air quality without calibration.

With compact and small body, this Breakout SGP40 Air Quality sensor is very suitable for indoor projects that will be used for a long time, such as refitting air purifiers, kitchen hoods, etc. Besides, we provide you with C and Python libraries for using with different main-controllers.

Note: VOC index is obtained by converting the detected ethanol equivalent in air.

Jargon buster

Plain-language definitions for the technical terms used above.

breakout
A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.
CMOSens
CMOSens is Sensirion’s integrated sensor technology that combines sensing elements and electronics in one package. It matters because it affects how the sensor measures temperature and humidity and how it is supported by the manufacturer’s libraries and datasheets.
I2C
I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
I2C address
An I2C address is the number a device uses so a microcontroller can tell it apart from other devices on the same I2C bus. It matters because two devices with the same fixed address may conflict if used together.
VOC
Volatile organic compounds are gases released from things like paints, cleaners, smoke, and some plastics. A VOC reading helps indicate indoor air quality, but it is usually an index or estimate rather than a direct identification of each chemical.
