The ADPD2140W is an optical sensor that detects and measures the angle of incident infrared light within a wide field of view and can be used in conjunction with an infrared light emitting diode (LED) to detect user hand movements or gestures.
The ADPD2140W has an illuminated, radiant sensitive area of 0.363 mm2 . The low diode capacitance and low dark current of the ADPD2140W allows optimal integration with the ADPD1080 photometric front end. The ADPD2140W requires four photodiode channels. Therefore it is recommended to use the ADPD1080BCPZ with the ADPD2140W
Packaged in a small, clear mold, 2 mm × 3 mm, 8-lead LFCSP, the ADPD2140W is specified over the −40°C to +105°C operating temperature range.
- Gesture for user interface control
- Light angle sensing
- Proximity sensing
Evaluation Kits (1)
The EVAL-ADPD2140Z evaluation kit allows users to interface with the ADPD2140 infrared (IR) light angle sensor, collect data from the ADPD2140, and evaluate gesture recognition and triangulation capabilities.
The evaluation kit requires the EVAL-ADPDM3Z evaluation board and the Applications Wavetool, a graphical user interface (GUI) that provides users with low level and high level config-urability, real-time data analysis, and user datagram protocol (UDP) transfer capability, which allows the EVAL-ADPDM3Z evaluation board to interface to a PC. The Applications Wavetool can be downloaded from the EVAL-ADPD2140Z evaluation board product page.
The USB port of the PC powers the EVAL-ADPDM3Z evaluation board and provides power to the EVAL-ADPD2140Z evaluation board. On-board voltage regulators provide voltage supplies for the ADPD2140.
The EVAL-ADPD2140Z evaluation board schematic indicates signal names for easy identification.
Full specifications for the ADPD2140 are available in the ADPD2140 data sheet, which should be consulted in conjunction with this user guide when working with the EVAL-ADPD2140Z evaluation board.
