Qwiic Spectral Sensor - AS7341

Added to your shopping cart

The AS7341 is an 11-channel spectral sensor from AMS that covers wavelengths between 350nm to 1000nm. It features eight channels that span the visible spectrum and there's a channel for Near IR, clear, and flicker detection up to 2kHz. Point a spectral sensor at an object and it measures the reflected or absorbed electromagnetic wavelengths.

The Qwiic Spectral Sensor also includes on-board IR and white LEDs that can be used to get a better spectral reading. A 4-bit GPIO drives those LEDs and can easily be controlled through software. The LEDs are also configurable to your unique project by cutting the jumper and soldering your own through-hole white and IR LEDs.

The AS7341 communicates over I2C and is mounted on the 1x1 Qwiic board you know and love. We've even got an Arduino Library ready to go!

This board is one of our many Qwiic compatible boards! Simply plug and go. No soldering, no figuring out which is SDA or SCL, and no voltage regulation or translation required!

We do not plan to regularly produce SparkX products so get them while they’re hot!

Experimental Product: SparkX products are rapidly produced to bring you the most cutting edge technology as it becomes available. These products are tested but come with no guarantees. Live technical support is not available for SparkX products. Head on over to our forum for support or to ask a question.
