The TRS1722, TRS1755, and TRS1766 are high-sensitivity reflective color sensors in red (630 nm), green
(567 nm), and blue (470 nm) — respectively — with light-to-voltage converters. Each device consists of a
colored LED light source, a photodiode light sensor with matching optical color filter, a transimpedance amplifier,
and on-board signal conditioning. Output voltage is directly proportional to the reflected light intensity on the
photodiode plus any ambient light (which may be considered noise).
