Evaluation Kit for TMD2725
General description
The TMD2725 Evaluation Kit comes with everything needed to evaluate the TMD2725 proximity sensor module. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TMD2725 module daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the proximity sensor settings as the PIC takes the TMD2725 I²C digital outputs to calculate proximity.

TMD2725 Ambient Light Sensor
TMD2725
The device features advanced proximity measurement and digital ambient light sensing (ALS). The package has been designed to accommodate a single small aperture approach. The 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 ALS photodiode has UV and IR blocking filters and a dedicated data converter producing 16-bit data. This architecture allows applications to ccurately measure ambient light which enables devices to calculate illuminance to control display backlight.
