DFRobot TMF8801 Time-of-Flight Distance Ranging Sensor Module

The DFRobot TMF8801 Time-of-Flight Distance Ranging Sensor is a high-precision module designed for accurate non-contact distance measurement. Based on the advanced AMS TMF8801 sensor, it uses time-of-flight (ToF) technology to calculate distance by measuring the time difference between emitted and reflected light pulses. This method allows for reliable detection of objects from 2 cm to 250 cm (20 mm to 2500 mm), independent of the object's colour, texture, or surface reflectivity.

A standout feature is its high dynamic range and robust performance in challenging lighting conditions. The sensor can operate accurately in complete darkness and maintains functionality under direct sunlight, thanks to on-chip sunlight rejection filters that minimise background light noise. Accuracy is maintained within ±5% across its operating range. The integrated microcontroller handles all complex algorithms on-chip, requiring no external optics or processing, simplifying integration into your projects.
