What is the technology used to detect the smoke? null

Nest Protect uses a Split-Spectrum Sensor capable of detecting fast-flaming fires and smoldering fires using a 450nm wavelength of light to detect the tiny particles created by fast fires. It also uses a 880nm infrared wavelength to look for larger particles created by smoldering fires. You can learn more about Split-Spectrum Sensor here: https://nest.com/support/article/What-is-the-Split-Spectrum-Sensor as well as get a more in-depth look in our Split-Spectrum Sensor White Paper available at the bottom of the previous link!

The website states the following; The Split‑Spectrum Sensor uses two wavelengths of light to detect smoke from both fast-burning and smoldering fires.
