TCS3701 Color & Proximity Sensor ams OSRAM TCS3701 Color and Proximity Sensor features ambient light and color (RGB) sensing in parallel with proximity detection. The device is housed in a low-profile 2.5x2.0x0.5mm package. The Ambient Light and Color Sensing function provides five concurrent ambient light sensing channels: Red, Green, Blue, Clear, and Wideband. The RGB and Clear channels have a UV/IR blocking filter. This architecture accurately measures ambient light. It enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance.
