Light Sensors

ams

ams light sensors are suitable for many applications that are used in the visible light spectrum or the IR range.

Detection of room brightness (ALS - ambient light sensing), color measurement (in the RGB color space), proximity detection (by using IR) and line arrays for "scan" applications are part of the standard portfolio.

In addition to the often used LTD products (light-to-digital), analog LTV (light-to-voltage) and LTF (light- to-frequency) products are still supported for highly dynamic applications (in terms of the light intensity and change of intensity).

ams provides parts for almost every application: mobile device display management (mobile phones, tablets), inpatient sector (TVs, computer monitors, medical diagnostic devices), industrial process Analysis (e.g. turbidity measurement of airborne particles), color control in LED lighting or in the print media.

Ambient Light Sensor (ALS)

Due to the special structure of the ALS products (dual-diode implementation) these devices offer a sensor response that is very similar the human eye. The result is that response to change in ambient brightness can be adjusted more easily to the human perception of brightness and this leads to improved user acceptance. A dynamic range of 8,000,000:1 (TSL2572x) or a direct LUX output (TSL4531x) are only 2 of the highlights in this sector.

Ambient Light Sensor & Proximity Detection

The combined ALS + Prox (proximity) products integrate the detection of surrounding brightness and an IR-based approximation detection e.g. for device activation or display / touch deactivation. The high sensitivity and high dynamic range of the sensors make detection in the near field behind dark glass and also over long distances possible. ams offers finished modules with IR diode (TMD27xx) and solutions with built-in IR LED driver (TSL27xx) to be as flexible as possible for many law enforcement requirements.

Color Sensor

ams colour sensors are perfectly suited to accurate colour determination. Up to 4 colour channels (RGBC - red / green / blue / clear) are available. For applications such as pulsed LED lights some products have a synchronization input to enable a measurement that is appropriate to the PWM signal of the LED driver. With IR filters, the influence of unwanted light sources in the environment is minimized (sunlight, other lights).

Gesture, Color & Proximity Detection

The Gesture product family features advanced Gesture detection, Proximity Detection, Digital Ambient Light Sensing (ALS), Color Sensing (RGBC), and optical pattern generation/transmission for Barcode broadcast. The IR Gesture sensor modules provide a highly integrated solution offering five essential functions for maximizing the end user experience in advanced communications and consumer electronics enabling a coherent display and touchless interface. Gesture detection utilizes four directional photodiodes to sense IR energy (sourced by the integrated LED) to convert physical motion information (i.e. velocity, direction and distance) to digital information. The Gesture engine incorporates a wide range of device gesture requirements and accurate sensing with minimized power consumption and noise through adjustable IR LED timing and enhanced gesture algorithms.
