Evaluation Kit for TMD2620
The TMD2620 Evaluation Kit comes with everything needed to evaluate the TMD2620 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 TMD2620 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 TMD2620 I²C digital outputs to calculate proximity.

TMD2620 Proximity Detection Module
The device is an advanced proximity sensor. 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.
