Color Sensor Optimized For Smartphones

Color Sensor Optimized For Smartphones
ROHM Semiconductor

The BH1745NUC color sensor is groomed for display-equipped devices such as smartphones and tablets capable of detecting the color temperature, brightness, and RGB components of ambient light. As per its maker, the sensor leverages original infrared removal technology and computing methods to achieve the industry's highest infrared cutoff characteristics, reducing the effects of infrared rays by over 10x compared with comparable components. Conventional color sensors require a transparent optical window in order to accurately detect visible (i.e. RGB) light. However, the design trend in many smartphones and portable devices is to adopt dark optical windows that, although more stylish, make it difficult to precisely detect colors, since less visible light gets through and the light that does permeate gets mixed in with IR rays. In response, the BH1745NUC’s compatibility with dark optical windows provides greater design flexibility. Pricing is $0.72 each/4,000. A datasheet is available at
