TMG49033

The main features of the TMG4903 sensor module described in the datasheet include: - Gesture detection - Color sensing - Ambient light sensing - Cell phone touch screen disable - Mechanical switch replacement - 1D bar code emulation - Universal remote control - 2D and 3D gesture and proximity detection - Automatic sample rate adjustment - Self-maximizing dynamic range - Ambient light rejection - Advanced crosstalk compensation - AFE saturation flag

The Ambient Light and Color Sensing feature of the TMG4903 sensor module provides Red, Green, and Blue (RGB) ambient light sensing with a Clear reference (C). It has a color diode array with a UV/IR blocking filter and parallel ADCs to produce simultaneous 16-bit results. This function accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance.

The Gesture and Proximity sensing function of the TMG4903 sensor module synchronizes IR emission and detection to sense gesture and proximity events. It features automatic high sample rate activation, self-maximizing dynamic range, ambient light subtraction, advanced crosstalk cancellation, 14-bit data output, 32-dataset FIFO, and interrupt-driven I²C communication. The sensitivity, power consumption, and noise can be optimized with adjustable IR LED timing and power. The gesture engine is capable of 3D detection of motion and position, with configurable gesture interrupts to reduce I²C communication load. The proximity engine recognizes detect/release events and produces a configurable interrupt whenever proximity result crosses upper or lower threshold settings.
