Exceeded expectations
The 940nm laser is truly invisible, which is great for consumer products where you don't want a visible red dot. Accuracy within 3mm is spot on as advertised. Very happy with this purchase.

Great range, easy I2C setup
Setup with my Arduino was straightforward using the standard library. It consistently hits the 4-meter mark indoors. Only giving 4 stars because the datasheet could be clearer on voltage regulation if powering directly from 5V.

Best ToF sensor for beginners
I was worried about the complexity of laser sensors, but this module made it easy. Plenty of example code available online. The measurements are stable and repeatable.

Solid performance for prototyping
We used these for a quick prototype of a conveyor belt counter. They worked flawlessly for weeks. Not sure about long-term durability in harsh industrial environments, but for lab use, it's excellent.

Perfect for robotics projects
This sensor is incredibly accurate for its size. I used it on a small line-following robot to detect obstacles, and the response time is fantastic. The optical cover really helps reduce noise from ambient light.

Lightweight and reliable
Weight is negligible, which is crucial for my drone altitude hold project. It performs well even in moderately lit rooms. Highly recommend for anyone needing precise short-to-medium range data.
Q: Does this come with a library for Python/Raspberry Pi?
A: Yes, STMicroelectronics provides an official API that has been ported to Python for Raspberry Pi. There are also several community-maintained libraries available on GitHub that simplify integration.
Q: Can this sensor work outdoors in direct sunlight?
A: While the sensor has good ambient light immunity, direct sunlight can saturate the receiver. It is best suited for indoor use or shaded outdoor areas. In direct sun, the effective range may drop significantly below 4 meters.
Q: Is a logic level shifter required for 5V microcontrollers?
A: Yes, the VL53L1X operates at 2.6V-3.5V. If you are using a 5V board like an Arduino Uno, you should use a logic level shifter for the SDA and SCL lines to prevent damage to the sensor.
Q: Can multiple sensors be used on the same I2C bus?
A: Yes, but since they share the same default I2C address, you must change the address of subsequent sensors via software initialization before connecting them to the bus simultaneously. The API supports this feature.
Q: What is the minimum distance this sensor can measure?
A: The minimum measurable distance is typically around 30mm to 40mm. Objects closer than this may not be detected reliably or may return invalid readings.
