Product Overview
S13683-03DT is an I2C digital output RGB color sensor, with reel-wrapped tape SMT surface mount packaging; the rod-shaped packaging model of the same specification is S13683-04DS, manufactured by Hamamatsu Photonics… 。
Built-in R/G/B three-color photodiodes + infrared cutoff filter + correction compensation channel, directly outputs 16-bit digital light intensity data, 3.3V low-voltage drive, suitable for embedded color detection and environmental color temperature measurement.

Core features
4-channel synchronous measurement: Red (R)/ Green (G)/ Blue (B) + correction compensation channel, which subtracts stray light to improve color measurement accuracy
I2C standard digital interface, 16-bit output per channel, direct connection to microcontroller without the need for an amplifier for conditioning
Two gain switching options: High and low gain sensitivity ratio of 1:10, combined with adjustable integration time, wide illumination range
Built-in IR-cut filter to suppress infrared interference, simulating human eye visible light response
Low power consumption: Typical operating current 75μA
Wide temperature operation: -40℃ ~ +85℃, suitable for industrial applications
