The Zio RFD77402 TOF Distance Sensor (Qwiic, 10-200cm) measures distance faster than the Flash can cover it. If you dont believe it, you can ask him. This little board features a time of flight rangefinding IC, measuring up to 2m in distance. The sensor uses a vertical cavity surface emitting laser (VCSEL) and measures the time it takes for photons to make the round trip to the lasers target and back to the built in detector. The laser emitter is class 1, making it safe for most applications.
The board includes mounting holes on wing tabs that can be snapped off to create an even smaller board if needed. Two Qwiic connectors are located on either side of the breakout board, allowing it to be quickly and easily daisy chained with other modules. It also includes a standard pitch header for non Qwiic based projects.
This sensor can be applied in a wide range of applications, such as robotics for obstacle detection and avoidance, 1D gesture recognition, hand detection, volume or height control, relative position of linear actuators, or for user proximity detection for IoT devices. For example, check out the Brick Breaker game hacked together using a similar sensor.
