Sensor module packs design flexibility into a small footprintElectronics distributor Mouser Electronics is now stocking the TMD3700 proximity and color sensor module from ams. This optical sensor module senses RGB colour, ambient light, and proximity to provide OEMs with design flexibility and the ability to provide a better display viewing experience — all in a small footprint for colour and proximity modules, making the device’s performance and small space requirements ideal for next-generation mobile devices with ultra-thin profiles and narrow bezels.

The ams TMD3700 sensor module offers a 4.00 × 1.75mm footprint with a height of just 1.00mm. Its wide 45-degree field-of-view, ambient light sensing accuracy of ±10 per cent, and operating range of 200 mlx to 60 klx behind dark glass all enable smartphones to measure the surrounding light environment and automatically adjust display color and brightness for optimal viewing.

The unit's color sensor channels each have ultraviolet (UV)- and infrared (IR)-blocking filters and a dedicated converter that allows simultaneous data capture necessary for accurate measurements. The combination of photopic colour and ambient light sensing enables smartphones to perform real-time adjustment of the display properties to achieve the best visual color accuracy.

Additional features enable dynamic elimination of both electrical and optical crosstalk, which produces reliable proximity detection — a function that allows smartphones to disable the touchscreen display when held close to the user’s face. In addition, the module’s integrated IR LED is calibrated for maximum performance and consistent operation. And the TMD3700 modules are supported by an evaluation kit, also available from Mouser Electronics.
