Evaluation Kit for TMD2712
The TMD2712 Evaluation Kit comes with everything needed to evaluate the TMD2712 ALS / proximity sensor module. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with a USB cable), a TMD2712 module daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the ALS / proximity sensor settings as the PIC takes the TMD2712 I²C digital outputs to calculate ALS and proximity.

TMD2712 ALS and Proximity Sensor
The TMD2712 features proximity detection and digital ambient light sensing (ALS). The extremely tiny 1mm x 2mm module incorporates an IR VCSEL and factory calibrated VCSEL 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 VCSEL). Detect/release events are interrupt driven, and occur when proximity result crosses upper and/or lower threshold settings. The proximity engine features a wide range offset adjustment to compensate for unwanted IR energy reflection at the sensor. Proximity results are further improved by automatic ambient light subtraction. The ALS and IR photodiodes have dedicated data converters producing 16-bit data. This architecture allows applications to accurately measure ambient light which enables devices to calculate illuminance to control display backlight.
