ams TMD3725 Color Sensor Module

Product features

The TMD3725 features advanced proximity measurement, color sense (RGBC+IR), and digital ambient light sensing (ALS). The package has been designed to accommodate a “single hole” aperture approach. 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 user’s 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 ALS detection feature provides photopic light intensity data. The color photodiodes have UV and IR blocking filters and converts photodiode current into dedicated integrating data converters producing 16-bit data. This digital output can be interfaced with a microprocessor where illuminance and color temperature can be calculated to control a displays backlight and chromaticity.
