Optical Sensors

optical motion sensoroptical flowSPIfar fieldCOBdrone

PMW3901MB-TXQT is a far-field optical motion sensor for X-Y movement detection from 80 mm to infinity, using a 2 MHz 4-wire SPI interface.

Best for

  • Far-field optical-flow and motion sensing
  • Drone and GPS-denied positioning designs
  • Systems needing SPI X-Y motion output

Avoid if

  • The target surface is closer than 80 mm
  • The design cannot use the specified optical assembly
  • Operation is required outside 0 °C to 40 °C without separate validation

Check before use

  • Use VDDIO at or above VDD
  • Allow at least 50 ms from reset to valid motion
  • Write the documented performance-optimization registers after power-up
