The CCS811 Air Quality Breakout is a digital gas sensor solution that senses a wide range of Total Volatile Organic Compounds (TVOCs), including equivalent carbon dioxide (eCO2) and metal oxide (MOX) levels. VOCs are often categorized as pollutants and/or sensory irritants and can come from a variety of sources like construction materials (paint, carpet, etc.), machines (copiers, processors, etc.) and even people (breathing, smoking, etc.). This breakout is intended for indoor air quality monitoring in personal devices such as watches and phones, but we’ve put it on a breakout board so you can use it as a regular I2C device.
The SparkFun Sound Detector is a small and very easy-to-use audio sensing board with three different outputs. The Sound Detector not only provides an audio output, but also a binary indication of the presence of sound and an analog representation of its amplitude. The three outputs are simultaneous and independent, so you can use as many or as few as you want at once.
The SparkFun AS7262 Visible Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7262 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board --- simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic Shields, then stack the board on a development board. You’ll be ready to upload a sketch to start taking spectroscopy measurements in no time.
The SparkFun AS7263 Near Infrared (NIR) Spectral Sensor Breakout brings spectroscopy to the palm of your hand, making it easier than ever to measure and characterize how different materials absorb and reflect different wavelengths of light. The AS7263 Breakout is unique in its ability to communicate by both an I2C interface and serial interface using AT commands. Hookup is easy, thanks to the Qwiic connectors attached to the board --- simply plug one end of the Qwiic cable into the breakout and the other into one of the Qwiic shields, then stack the board on a development board.

The SparkFun ESP32 Thing Motion Shield is a versatile, motion-sensing addition to our ESP32 Thing. With the Motion Shield's onboard LSM9DS1 IMU, small movement changes can easily be detected, while larger movements and time traveled can be detected with the addition of a GPS module via a large JST port. In addition, we have added breakout pins to attach any serial device, as well as a microSD card slot to log all of your data. All you need to do is solder on headers, and your ESP32 Thing Motion Shield will be ready to detect any type of movement!
The SparkFun H3LIS331DL Triple Axis Accelerometer Breakout is a low-power, high-g accelerometer with I2C and SPI interface options. Though not necessarily good at detecting minute changes, the H3LIS331DL is great for grueling conditions that normal accelerometers aren't suited for. With a shock survivability of 10000g and a handy sleep-to-wake function, the H3LIS331DL breakout makes the perfect board for shock and collision detection as well as impact recognition and logging.
This is not your normal Passive Infrared (PIR) sensor! The SparkFun AK9753 Human Presence Sensor Breakout is a Qwiic-enabled, 4-channel Nondispersive Infrared (NDIR) sensor. Each channel has a different field of view, so not only can the AK9753 detect a human, but it can also tell which direction the person is moving. To make it even easier to use this breakout, all communication is enacted exclusively via I2C, utilizing our handy Qwiic system. However, we still have broken out 0.1" spaced pins in case you prefer to use a breadboard.
The BME680 from Bosch is a powerful sensor capable of sensing humidity, barometric pressure, temperature and indoor air quality. The BME680 can communicate over SPI or I2C (default). The SparkX carrier board provides jumpers to select between communication protocols (SPI or I2C) as well as the ability to change the I2C address and remove the I2C pull up resistors. The carrier board also incorporates two Qwiic connectors so you can start talking to the board immediately - no soldering required!
If you need to add user input without using a button, then a capacitive touch interface might be the answer. The AT42QT1011 SparkFun Capacitive Touch Breakout offers a single, momentary capacitive touch button with easy-to-use digital I/O pins.
The APDS-9301 Ambient Light Sensor Breakout is an I2C-compatible luminosity sensor board that converts light intensity to a digital output signal. This breakout is fairly simple and has been specifically designed with only a few ancillary passive components in addition to the APDS-9301 IC itself. All readings are returned to your chosen microprocessor in lux, providing precise Illuminance measurement under diverse lighting conditions.
