TFmini Infrared Time of Flight Distance Sensor

Product ID: 3978

We've got many distance sensors, and the TFmini Distance Sensor is a nice addition. This sensor bounces light off objects and returns the distance in centimeters. It's a nice compact plastic package, with UART serial output. Please note that the company calls this a "LiDAR" but it is not a true LIDAR. Instead, its a time-of-flight (ToF) infrared sensor like the...
