Time-of-Flight Sensor


  • Distance Measurement Range from 20 to 250 cm
  • True Direct Time-of-Flight Measurement
  • Fast Compact Time-To-Digital Converters
  • High Accuracy Distance Measurement (5%) - 1 mm Resolution

The TMF8801 is a robust true direct time-of-flight (ToF) sensor system that offers highly accurate depth accuracy detection through a sub-nanosecond light pulse and an antialiasing "stop-watch" method to measure round-trip time of the pulse. It provides single-zone detection of an object, regardless of the color, reflectivity, and texture of the object. An integrated microcontroller is featured with all algorithms included on-chip with no need for external optics. Ultra-compact technology use is featured through the industry‘s smallest modular package size of 2.2 x 3.6 x 1.0 mm.
