TMD3702VC - Color and Proximity Sensor

Description

The TMD3702VC

Features

  • proximity detection, color sense (RGBC+IR), and digital ambient light sensing (ALS). The extremely narrow 1.44mm 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.

TMD3702VC Narrow ALS, Color and Proximity Sensor Module General Description The TMD3702VC features proximity detection, color sense (RGBC+IR), and digital ambient light sensing (ALS). The extremely narrow 1.44mm 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.
