Product Detail

The PAA3905E1-Q by Pixart is an optical motion tracking sensor designed for object motion sensing. It features a wide working distance from 80mm to infinity and requires no focal length calibration. The sensor can auto-detect challenging conditions such as checkerboards, stripes, glossy surfaces, and yawing. It outputs 16-bit motion data and includes a motion detect pin output. The sensor operates with a supply voltage of 1.8~2.1V and an interface voltage of 1.8~3.6V. It communicates via a 4-wire SPI and has a resolution range of 340@35mm to 790@15mm. The package size is 6.0*6.0*2.8mm.

Optical Motion Tracking Chip

PAA3905E1-Q: Optical Motion Tracking Chip

General Description

The PAA3905E1 is PixArt Imaging's optical motion tracking chip specifically designed for low light condition operation. The state of the art of architecture allows motion tracking under low light conditions as low as 5 lux. The chip supports a wide working distance of 80 mm to infinity under challenging conditions to cater for different far-field application needs and ambient conditions. It is suitable for far-field tracking applications in providing motion tracking with a stable hovering function for Drone.

Key Features

  • Wide working distance from 80mm to infinity
  • No focal length calibration required
  • Auto-detection of challenging conditions, e.g. checkerboards, stripes, glossy surface, and yawing
  • 16-bit motion data output with motion detect pin output
  • Internal oscillator
  • Raw Data Output through register read
  • Support synchronized multi-chip operation
  • Automatic switching of Operation Mode

Operation Modes

Mode Description Lux (Typ)
0 @ 126 fps Bright Mode for general motion tracking 60
1 @ 126 fps (Default) Low Light Mode for low light motion tracking 30
2 @ 50 fps Super Low Light Mode for super low light and low-speed motion tracking 5

Applications

  • Drone or other devices that require far-field motion detection and hovering stability
  • X-Y positioning in GPS denied environment
