ALS and proximity sensor accurately measures ambient light

Update: August 6, 2023

Mouser now stocks the TMD2712 ambient light and proximity sensor from ams.

The sensor includes an IR VCSEL and factory-calibrated VCSEL driver in a remarkably tiny 1mm x 2mm module. The device provides proximity detection that offers object detection by photodiode detection of reflected IR energy (sourced by the integrated VCSEL).

The proximity engine provides broad range offset adjustments to compensate for unwanted IR energy reflection at the sensor. Proximity results are improved further by automatic ambient light subtraction.

Applications for the sensor include mobile phone display and proximity management, and user proximity detection and ambient light measurement for wearables.
