Reliable industrial performance

We deployed ten of these units on our assembly line counters. They have been running 24/7 for a month without drift. Only giving 4 stars because the documentation could be more detailed.

Easy I2C implementation

The register map is straightforward. I had it reading distance values within an hour of unboxing. No complex calibration required out of the box.

Great value for ToF technology

Compared to other ToF sensors in this price range, the 7-meter range is impressive. It handles different surface reflectivities better than expected.

Lightweight and precise

Used this for altitude hold on a custom drone build. The fast response time makes a noticeable difference in stability during rapid ascents.

Perfect for robotics projects

This sensor integrates seamlessly with our Arduino-based robot. The I2C communication is stable, and the millimeter-level accuracy is exactly what we needed for obstacle avoidance.

Good consistency

Testing shows very low variance in repeated measurements. The form factor is compact enough for tight enclosures. Would recommend for prototyping.

5 FAQ

Q: How does ambient sunlight affect performance?

A: As an industrial-grade sensor, it has good ambient light immunity. However, direct intense sunlight may reduce the effective maximum range slightly. Indoor use yields optimal results.

Q: Does this module work with 5V logic levels?

A: The sensor operates at 3.3V. While the I2C lines are often tolerant, we strongly recommend using a logic level shifter if connecting to a 5V microcontroller to ensure longevity.

Q: Can this measure through glass?

A: No, ToF laser sensors generally cannot measure distance through transparent materials like clear glass as the laser passes through rather than reflecting back. It works best on opaque surfaces.

Q: What is the sampling rate of this sensor?

A: The maximum sampling rate is approximately 20Hz (50ms per measurement), depending on the I2C bus speed and your host controller's processing time.

Q: Is there a library available for Raspberry Pi?

A: Yes, we provide a Python library compatible with Raspberry Pi OS on our GitHub repository. It includes examples for continuous ranging and single-shot modes.
