Color measurement using RGB digital color sensors and photodiodes

RGB digital color sensors: Affordable yet accurate color sensor options

RGB color sensors are often the most cost-effective solution for colorimetry requiring a tristimulus or color temperature type of sensor, especially when a spectrometer’s capabilities would be excessive or expensive for your application parameters.

Additional characteristics to consider include:

  • Infrared, red, green, and blue spectral sensitivity
  • Form factor and physical size constraints

We offer two types of RGB color sensors with digital output: digital and I2C-compatible color sensors.

 

Digital color sensors measure red, green, and blue colors simultaneously. Some models are also sensitive to near-infrared wavelengths. They feature a 12-bit digital output and two-step sensitivity switching (low/high) to cover a wide range of light levels. Alternatively, I2C-compatible color sensors measure RGB colors sequentially. Some models are also sensitive to near-infrared wavelengths. They feature an inter-integrated circuit (I2C) interface, 16-bit digital output, and two-step sensitivity switching (low/high) to cover a wide range of light levels.

RGB photodiodes: Accurate, low cost analog color sensors for varied applications

These 3-channel photodiodes are sensitive to red, green, and blue regions of the electromagnetic spectrum and are ideal for applications that require less than a full spectrum of information. They feature a very small package and low unit cost.

 

When selecting an RGB photodiode, it’s important to consider the following detector characteristics:

  • Spectral sensitivity required for your application
  • Form factor and physical size constraints

Our products provide an analog output for each color, which must be processed by adding external circuits.
