The SGP40 Multi-Pixel Gas Sensor is a fully integrated MOX gas sensor. This is a very fine air quality sensor from the sensor experts at Sensirion, with I2C interfacing so you don't have to manage the heater and analog reading of a MOX sensor. It combines multiple metal-oxide sensing and heating elements on one chip to provide more detailed air quality signals. This can detect a wide range of Volatile Organic Compounds (VOCs) and H2 and is intended for indoor air quality monitoring. The SGP40 has a 'standard' hot-plate MOX sensor, as well as a small microcontroller that controls power to the plate, reads the analog voltage and provides an I2C interface to read from.
The surface-mount sensor is soldered onto a custom made PCB in the STEMMA QT form factor, making them easy to interface with. The STEMMA QT connectors on either side are compatible with the SparkFun Qwiic I2C connectors. This allows you to make solderless connections between your development board and the SGP40 or to chain it with a wide range of other sensors and accessories using a compatible cable. QT Cable is not included.
STEMMA QT / Qwiic 4-pin 1mm Pitch White Female Connector Cable 150mm Long - Both Side can be purchased seperately.
