ACEBOTT Support Bright Light Induction Electronic Component Color Sensor Module RGB Recognition Optical Color Sensor for Arduino
Product Description
Products Description
The Color Sensor is an optical sensing to recognize the surface color of an object. Support red, green, blue (RGB) three basic colors, support bright light induction, can output the corresponding specific value, restore the actual color. The onboard comes with two bright LEDs, which allows the sensor to use normally in the case of low ambient light, realizing the function of “filling light filling”.
Application reference: color calibration device, color printer, plotter, etc.

Frequently Asked Questions
What is the primary function of this Color Sensor module?
The module uses optical sensing to recognize surface colors by measuring Red, Green, and Blue (RGB) components and bright light values, accurately reconstructing the actual color of the target surface.
How does the sensor perform in dim or dark environments?
It includes two integrated high-brightness LEDs that provide auxiliary illumination (fill light), allowing reliable and precise color recognition even in low ambient light conditions.
What is the optimal detection distance for accurate readings?
The optimal detection distance ranges between 3mm and 10mm from the sensor face to the measured surface.
How do I interface the Color Sensor with an ESP32 board?
Connect VCC to the 5V power pin, GND to Ground, and wire the SCL and SDA pins directly to the corresponding I2C communication pins on your ESP32 controller or expansion board.
What communication protocol does the module support?
The sensor operates using the standard I2C (12C) serial bus protocol, requiring only two communication lines (SDA and SCL) for convenient micro-controller integration.
What are the operational temperature limits of the sensor?
The module is designed to reliably operate across a wide industrial temperature range from -30°C up to +70°C.
