The TMF8801 is a tiny, easy to use, time-of-flight sensor for measuring distances up to 2.5m. It uses a Class 1 IR VCSEL for excellent performance in dark and sunlit applications. Minimum measuring distance is 2cm. Compared to other sensors like the VL53L1X, the TMF8801 is beautiful in its simplicity. The interface is fully documented and our Arduino library contains example sketches to get you up and running quickly.
With an advertised range of 20 to 2500mm*, the TMF8801 also offers two highly configurable GPIO able to be used for one-shot-measuring, sensor disable, as well as general input and output (with both high/low drivers).
Note: In practice we have found the max range to be around 600mm. We have addressed this with AMS but haven't received a resolution.
The TMF8801 comes calibrated from AMS for optimal read range out of the box. But if the sensor is mounted behind plastic or glass, examples are provided in the SparkFun library to recalibrate the sensor.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.
