The TMF8801 in particular can do 20mm to 2.5 meters at 33 Hz update rate.\u003c\/p\u003e\n\u003cp\u003eThe sensor contains a very tiny invisible laser source and a matching sensor. The TMF8801 can detect the \"time of flight\", or how long the light has taken to bounce back to the sensor. Since it uses a very narrow light source, it is good for determining distance of only the surface directly in front of it. Unlike sonars that bounce ultrasonic waves, the 'cone' of sensing is very narrow. Unlike IR distance sensors that try to measure the amount of light bounced, the TMF is much more precise and doesn't have linearity problems or 'double imaging' where you can't tell if an object is very far or very close.\u003c\/p\u003e\n\u003cp\u003eOne nice thing about this sensor is that while it does require a firmware 'patch' on boot and the SRAM usage is also much lighter, so it fits easily in small memory boards like the ATmega328. You can use it on many 8-bit microcontroller devices.\u003c\/p\u003e\n\u003cp\u003eThe sensor is small and easy to use in any robotics or interactive project. Since it needs 3.3V power and logic we put the little fellow on a breakout board with a regulator and level shifting. You can use it with any 3-5V power or logic microcontroller with no worries. Works great with the \u003cstrong\u003e3.3V logic level of a Feather, or the 5V level of a ATmega\u003c\/strong\u003e, this breakout is ready to work with most common microcontrollers or SBCs. and since it speaks I2C, you can easily connect it up with two data wires plus power and ground. \u003c\/p\u003e\n\u003cp\u003eAs if that weren't enough, we've also added\u003ca href=\"https:\/\/www.sparkfun.com\/qwiic\"\u003e SparkFun qwiic\u003c\/a\u003e compatible \u003cstrong\u003e\u003ca href=\"https:\/\/learn.adafruit.com\/introducing-adafruit-stemma-qt\"\u003eSTEMMA QT\u003c\/a\u003e\u003c\/strong\u003e connectors for the I2C bus \u003cstrong\u003eso you don't even need to solder.\u003c\/strong\u003e Just wire up to your favorite micro with a plug-and-play cable to get ToF data ASAP.
