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 … read more
Hi, - in regards to the while/grey you speak of. Would this work detecting the contours of a persons face as i drag across a 6x8 grid (logging the distance at each grid square). or up to 60x80 grid even.
I am replicating a project of 3d scanning. i will input the values to its designated colour as a visual representation.
Many thanks.
P.s. I am using a micro:bit, using aduino software
P.s.s The device would be only maximum 10cm away from the face if this helps measure contours.
Having a look the VL6180X seems to be the sensor that would work best.
Its rated range is 5-100mm so would fit right in the window you need.
As for interference of multiple sensors, it’s hard to say.
I wasn’t able to find much in my quick look through the datasheet.
With how long it takes light to travel a 200mm round trip it’d say the probability of multiple sensors interfering with each other would be low depending on how each sensor was configured.
Hi Aaron
The dominant factor here would be the antenna beam pattern and frequency selectivity.
If you happened to have 2 sensors on the same frequency and overlapping beam width then you would certainly get interference.
This sensor is a laser so if your “spot size” is small enough and does not overlap you stand a good chance of being interference free. The devices could even send out a code so it only responds to its own code which would be better still. I don’t know about that one and I have not gone into it that deeply so it is something to look at.
Cheers Bob
