Introduction
The Gravity: 8*8 64-Pixel Matrix Time-of-Flight (ToF) Sensor is a compact and efficient 3D depth-sensing solution that bridges the gap between simple distance sensors and complex depth cameras. Powered by onboard firmware running on an RP2040 microcontroller, it delivers real-time depth data across an 8×8 matrix of 64 points within a 60° field of view, with a detection range of up to 3.5 meters. Featuring low power consumption and plug-and-play compatibility, it is well-suited for robotics, interactive art, gesture recognition, and smart automation. With support for Arduino, micro:bit, ESP32, Raspberry Pi, and LattePanda, it enables the development of advanced applications such as intelligent obstacle avoidance, contactless gesture control, and immersive interactive installations.

3D Depth Perception at the Perfect Balance Point
This 3D robot obstacle avoidance sensor bridges the gap between basic ultrasonic sensors and high-cost AI depth cameras. Instead of seeing a single point, it generates a 64-pixel depth map that provides context—the obstacle, the open path, the edge of a table. This enables smooth, intelligent navigation without the complexity and processing demands of advanced cameras. With affordable pricing and ultra-low power usage, it offers the “just right” level of 3D vision for a wide range of creative projects.
Unmatched Compatibility for Maker Projects
This Matrix ToF proximity sensor was built for the way makers work, designed to connect to virtually anything in the workshop.

Expandable Platform for Advanced Development
In addition to plug-and-play use, the 64-Pixel Matrix ToF Vision Sensor can serve as a flexible development platform. Its onboard RP2040 processor allows developers to load custom firmware or run lightweight machine learning models (TinyML), making it possible to recognize specific gestures, detect movement patterns, or add new features directly on the sensor itself. With open-source schematics and comprehensive documentation, the module can be tailored for advanced robotics, IoT, and AI-driven applications, offering far more than a fixed-function sensor.

I'm still working on getting the most out of this, but I have worked through all of the functionality. It's not just that it does what it says it does that makes this sensor so good. It's the data that it produces. It gives a grid of data for all 64 points which is rather rich. Better than that though, it is fast and very accurate. I'm using a Pi 02W to operate it and I'm working on a system which will analyse the data as it flows and I can pattern match the movement directionally. There will be two of these at the front of my property and I will be able to see when a person enters the proprty, where they start from and the direction(s) that they walk in. The sensor itself doesn't give me all of that, the Pi does, but I couldn't achieve that without the rich, fast, accurate data flow. I cannot find a similar sensor at this price which can do this well.
