Evaluation Kit for TMD2755
The TMD2755 Evaluation Kit comes with everything needed to evaluate the TMD2755 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 TMD2755 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 TMD2755 I²C digital outputs to calculate proximity.

TMD2755 ALS and Proximity Sensor
The TMD2755 features proximity detection and digital ambient light sensing (ALS). The extremely narrow 1.1mm 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.
