Evaluation Kit for TMD2772
The TMD2772 Evaluation Kit comes with everything needed to evaluate the TMD2772 proximity and ambient light sensor. The evaluation kit comprises of a main controller board with a PIC microcontroller, an industry standard USB 2.0 interface (with an USB cable), a TMD2772 daughter card, "plug-n-play" USB HID class drivers, software documentation, and GUI software allowing users to control the ALS and proximity sensor settings as the PIC takes the TMD2772 I2C digital outputs to calculate ALS illuminance in lux approximating the human eye response.
TMD27723 Ambient Light Sensor
The TMD2772 family of devices provides digital ambient light sensing (ALS), a complete proximity detection system, and digital interface logic in a single 8-pin surface mount module. The devices are register-set and pin-compatible with the TMD2771 family of devices and include new and improved ALS and proximity detection features. The ALS enhancements include a reduced gain mode that extends the operating range in sunlight. Proximity detection includes improved signal-to-noise performance and more accurate factory calibration. A proximity offset register allows compensation for optical system crosstalk between the IR LED and the sensor. To prevent false proximity data measurement readings, a proximity saturation indicator bit signals that the internal analog circuitry has reached saturation.
