Time of flight sensor

No idea what "could" use it for, but super cool

https://www.adafruit.com/product/3316

The VL53L0X is a Time of Flight distance sensor like no other you've used! The sensor contains a very tiny invisible laser source, and a matching sensor. The VL53L0X 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 VL53L0x 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.

This is the 'big sister' of the VL6180X ToF sensor, and can handle about 50mm to 1200mm of range distance. It also includes a lux sensor. If you need a smaller/closer range, check out the VL6180X which can measure 5mm to 200mm.

The sensor is small and easy to use in any robotics or interactive project. Since it needs 2.8V 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. Each order comes with a small piece of header. Solder the header onto your breakout board with your iron and some solder and wire it up for instant distance-sensing-success!

Communicating to the sensor is done over I2C with an API written by ST, so its not too hard to port it to your favorite microcontroller. We've written a wrapper library for Arduino so you can use it with any of your Arduino-compatible boards.

Maybe an enhanced form of audio gain control (AGC) that detects how far your mouth/face is from a microphone and "optimizes" the gain for when you need to talk close to the mic, but do not want to overdrive your audio or if you are a low talker, give a prompt that you are too far from the microphone.

Not sure how I feel about "lasers" blasting my face though. >:)

MPET integration #758 Aaron?

  • Nice! <---- Value added post.

  • Furthest distance is about 4ft which isn't very far. But I wouldn't use this for a face detection distance circuit either.. Maybe farmbot.. ;) Hambot wouldn't need it either unless we wanted to use it as a deer detector in the garden.. hmmmm.... Shotgun and VL53L0X... Oh.. oops, Uncle came to visit.. Nahh.. rethinking...
