[SOLVED] Distance Sensor datasheet

thomas.bmichel · June 8, 2018, 12:31pm

Hello,

I used the gopigo3 robot this year in class, and I will have soon to do a presentation of my project.
I have been looking for the distance sensor datasheet or characteristics on the internet but I found nothing excepted the sensor’s range.

I would like to know its accuracy and if there is any documents about that sensor.

Can anyone help me with that ?

Thank you

Hi @thomas.bmichel,

The distance sensor is based on VL53L0X chip. Here’s a datasheet for it:

Also, the source code for this sensor can be found on our repository. The most important scripts are these:
