Great value, minor setup needed

Works well for obstacle avoidance on my custom drone. Had to tweak the baud rate settings initially, but once configured, it responds very quickly. Good build quality for the price.

Easy to integrate

As someone new to sensors, I appreciated how simple the wiring was. The TTL interface connected directly to my microcontroller without needing extra level shifters.

Fast sampling rate is a plus

The high sampling frequency allows for smooth data integration into our real-time mapping system. No lag detected during rapid movement tests.

Reliable for educational kits

We bought ten of these for our university lab. Students find the documentation clear enough to get started, and the modules have survived several semesters of heavy use without failure.

Solid performance indoors

Works flawlessly inside my workshop. I haven't tested it extensively in direct sunlight yet, but indoor precision is exactly as advertised. Compact size fits easily into tight enclosures.

5 FAQ

Q: Can it measure through glass?

A: Laser TOF sensors generally struggle with transparent surfaces like clear glass because the laser passes through rather than reflecting back. It works best on opaque or semi-opaque surfaces.

Q: What protocol does the serial output use?

A: The module outputs data via standard asynchronous UART. The specific data frame format includes distance values, signal strength, and error codes, detailed in the downloadable datasheet.

Q: Does this module work with Raspberry Pi?

A: Yes, it works with Raspberry Pi. Since it uses UART TTL serial communication, you can connect it to the GPIO TX/RX pins. Just ensure you configure the serial port correctly in your OS settings.

Q: Is the laser safe for human eyes?

A: Yes, this module utilizes a Class 1 laser, which is considered safe for human eyes under normal operating conditions according to international safety standards.

Q: What is the maximum update rate?

A: The module supports a sampling frequency of up to 1000 Hz, allowing for very fast distance updates suitable for high-speed applications.
