Perfect for white balance tools
I am building a custom white balance meter for my photography setup. The 11-channel spectrum gives me exactly the data granularity I need to calculate accurate color temperatures.

Easy to use with Raspberry Pi
Connected this to my Raspberry Pi 4 without any issues. The Python examples on GitHub worked out of the box. The flicker detection feature is a nice bonus for lighting analysis.

Good documentation support
The datasheet is detailed, which helped a lot with my university thesis project. The only reason for 4 stars is that the breakout board pins are a bit tight for standard jumper wires.

Low power consumption
Running this on a battery-powered ESP32 node. The power management features allow for long deployment times. Highly recommended for environmental monitoring stations.

Incredible precision for hobbyist projects
This sensor module is fantastic. The spectral data is very consistent, and the I2C library provided makes integration with my Arduino project seamless. Perfect for building a custom colorimeter.

Great value, minor calibration needed
For the price point, the accuracy is impressive. We used it for preliminary light testing in our lab. Just note that you need to perform your own calibration against a reference source for high-stakes measurements.
Q: How do I handle the interrupt pin for flicker detection?
A: The INT pin can be configured via registers to trigger on specific events like flicker detection or new data ready. You need to set the appropriate bits in the interrupt enable register in your code.
Q: Does this module come with a built-in voltage regulator?
A: Yes, the GY-AS7341 breakout board includes an onboard LDO regulator, allowing you to power it directly from 3.3V or 5V logic levels safely.
Q: What is the maximum I2C clock speed supported?
A: The AS7341 supports Standard-mode (100 kHz), Fast-mode (400 kHz), and High-speed mode (3.4 MHz) I2C communication protocols.
Q: Can this sensor detect UV light?
A: No, the AS7341 is designed for the visible spectrum and near-infrared (approx. 400nm to 950nm). It does not have specific channels for Ultraviolet (UV) detection.
Q: Is there a Python library available for this sensor?
A: Yes, there are several open-source Python libraries available on GitHub compatible with Raspberry Pi and CircuitPython. Check the resources section on our product page for links.
