VL6180X operation

Posted on March 01, 2016 at 17:10I undesratnd that ''ST Time of Flight technology uses photon detectors to measure the time it takes a generated light pulse to leave our product, then reflect from a target and come back to our device.  Knowing the t...

VL53L0x ambient light sensitivity

Posted on August 03, 2017 at 10:30HiI am testing the VL53L0X time-of-flight sensor, in order to find out how resistant it is to ambient light and it turns out that if you point a light source with a high IR content (like a halogen light bulb) toward...

Optical issues for use of VL53L0X ToF sensor

Posted on December 01, 2017 at 09:38I would like to use the VL53L0X to determine the position of a linear position actuator (i.e., a device long and thin relative to its width).  Therefore, I would like to restrict the effective field of view of the...

How to decrease the VL53L0X FOV?

Posted on October 23, 2017 at 16:13Hello.Does anybody knows if is possible to decrease the VL53L0X FOV putting in front of It a short piece of plastic (dark?) pipe?Could it works enough fine or the cross-talk will become unacceptable?Any other optio...

Measuring VL6180X with close distances

Posted on August 16, 2017 at 16:36Hey,I am having the VL6180X Satellites sensor for ranging measurements. After connecting it, I receive some measurement values - but they are the wrong ones. The sensor isn't reacting to changes in a distance betwee...

Suggestion for compass

Posted on January 02, 2018 at 13:02Hi. Happy new year !I'd like to use one of ST compass + accelerometer chip (2 in 1) for implementing with one of analog device gyroscope in Kalman filter. Which sensor do you offer?  what is the criteria of choosin...

vl53l0x I2C tBUF min=1.3ms?

Posted on November 30, 2017 at 16:48We've noticed that the datasheet states the following about I2C timings:tBUF - Bus free time between transmissions must be minimum 1.3msFor a 400kHZ I2C transmission, that sounds quite a long wait between frames.....
