Product Description
TFmini Infrared Module
Product Overview
The TFmini is a compact and high-performance infrared distance sensor based on Time of Flight (ToF) technology. It integrates unique optical and electrical designs to deliver stable, precise, high-sensitivity, and high-speed distance detection. With its robust operating range, low power consumption, and UART communication interface, the TFmini is ideal for applications such as drone altitude holding and terrain following, machine control and safety sensing, and robot distance detection.
