TMD3700 Color, ALS and Proximity Sensor Module The device features advanced Proximity measurement, Digital General Description Ambient Light Sensing (ALS) and Color Sensing (CRGB). The slim module incorporates an IR LED and factory calibrated LED driver. The Proximity detection feature provides object detection (e.g. mobile device screen to users ear) by photodiode detection of reflected IR energy (sourced by the integrated LED). Detect/release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features offset adjustment registers to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction. The Color and ALS detection feature provides red, green, blue and clear light intensity data. Each of the C, R, G, B channels have a UV and IR blocking filters and a dedicated data converter producing16-bit data simultaneously. This architecture allows applications to accurately measure ambient light and sense color which enables devices to calculate illuminance and color temperature, control display backlight, and chromaticity.
