Raspberry Pi Multi-Spectrometer | AS7341 11-Channel Sensor
Raspberry Pi Multi-Spectrometer - AS7341 11-Channel Spectral Sensor Module for Color and Light Analysis
The Raspberry Pi Multi-Spectrometer is a spectral sensing module for color matching, light-source analysis, reflectance experiments, and optical education projects. It is commonly associated with AS7341-class 11-channel spectral sensing, which covers multiple visible channels plus clear, near-infrared, and flicker-related measurements.
This module fits Raspberry Pi and embedded Linux workflows, and it can also support I2C microcontroller experiments depending on the breakout interface. It pairs with the Raspberry Pi Pico W, general I2C systems, and display or logging projects based on OpenELAB controllers. For raw environmental sensing, compare it with the BME680 Sensor Board.
AS7341-class sensors are useful for relative spectral signatures rather than laboratory-grade spectrometry. According to ams OSRAM AS7341 references, the device covers approximately 350nm to 1000nm and communicates over I2C; calibrate with known light sources when comparing samples.

Application Scenarios
1. Linux I2C Detect
Check whether the module appears on the Raspberry Pi I2C bus.
sudo i2cdetect -y 1
2. Python I2C Register Probe
Read a byte from a known I2C address after confirming the address from documentation.
from smbus2 import SMBus
ADDR = 0x39
with SMBus(1) as bus:
value = bus.read_byte_data(ADDR, 0x92)
print(hex(value))
3. CSV Spectral Logger Skeleton
Use your AS7341 library output to write spectral rows for later analysis.
import csv
import time
with open("spectral_log.csv", "a", newline="", encoding="utf-8") as f:
writer = csv.writer(f)
while True:
channels = [0, 0, 0, 0, 0, 0, 0, 0]
writer.writerow([time.time()] + channels)
f.flush()
time.sleep(1)
