Product details

DFrobot offers an advanced level of sensors at an affordable cost than any other competitor brand in the market, making them ideal for the one who wants to start some Projects through Different types of sensors.

After finding Different types of sensors on market, we at have determined that DFrobot is one of the good brands that offer a wide range of sensors at an Appropriate price.

The TMF8801 is a time-of-flight (ToF) distance-ranging sensor that measures distance by measuring the time difference between light pulses. It allows for single-zone detection of an object regardless of its color, reflectivity, or texture. The sensor has a wide dynamic range and can detect objects at distances of up to 250cm. The device is capable of making highly accurate distance measurements within 5% and can operate in both dark and bright environments. A built-in histogram provides dynamic cover glass calibration and crosstalk compensation, and on-chip sunlight rejection filters reduce background light noise.

The TMF8801 outputs data through an I2C fast-mode communications interface and an integrated microcontroller, which is featured with all algorithms included on-chip with no need for external optics.

Interfacing the TMF8801 Sensor with Arduino:



  1. 21º FOI, detect the object closest to the center
  2. 20–2500mm distance sensing
  3. Enables dark and sunlight environment distance measurement within ±5%
  4. A built-in histogram for compensating for dirt and smudges on the cover glass
  5. 940nm VCSEL Class 1 Eye Safety
