By integrating multiple optical sensing functions and an IR LED in a module, the TMx4903 devices are said to reduce board space requirements and lower bill of material cost while delivering capabilities required by today's smartphones.
The module variants in the series, the TMD4903 and TMG4903, are said to perform accurate colour and proximity sensing, and integrate an IRBeam IR pattern generator. The generator emits remote control beam patterns for standards-compliant consumer products. Mobeam 1D barcode emulation for use at retail point-of-sale terminals is also supported.
The TMG4903 device is also said to provide the industry's most advanced touchless IR gesture-sensing capability. ams claims its 3D gesture technology enables the recognition of complex hand gestures, supplementing north-south and east-west 2D gestures supported by ams' TMG3992 gesture sensor.
Sensor module integrates multiple optical sensing functions
ams has launched the TMx4903 series of optical sensing modules that integrate multiple functions including universal remote control, barcode emulation, RGB colour sensing, proximity and 3D gesture detection in a 5.0 x 2.0 x 1.0mm package.
