Evaluation Board for TMD3719
The TMD3719 Evaluation Kit comes with everything needed to evaluate the TMD3719 ALS/Color and Flicker/Proximity detection sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with a USB cable), a TMD3719 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the proximity sensor settings as the PIC takes the I²C digital outputs to calculate proximity.
TMD3719 ALS/Color and Proximity Sensor
The ambient light and color sensing function provides six concurrent ambient light sensing channels: Red, Green, Blue, Clear, Leakage and Wideband. The RGBL and Clear channels have a UV/IR blocking filter. This architecture accurately measures ambient light and enables the calculation of illuminance, chromaticity, and color temperature to manage display appearance. The device integrates direct detection of ambient light flicker for 4 selectable frequency bins. Flicker detection is executed in parallel with ambient light and color sensing. The flicker detection engine can also buffer data for calculating other flicker frequencies externally. The proximity function synchronizes IR emission and detection to sense nearby objects. The architecture of the engine features self-maximizing dynamic range, ambient light subtraction, advanced crosstalk cancelation, and interrupt-driven I²C communication. Sensitivity, power consumption, and noise can be optimized with adjustable IR VCSEL timing and power. The proximity engine recognizes detect/release events and produces a configurable interrupt whenever the proximity result crosses upper or lower threshold settings.
