TFmini Plus LiDAR Distance Sensor – 0.1~12m Range, 1000Hz IP65 Waterproof, UART Interface, Compact Single-Point Laser Ranging for Open-Source Flight Controllers

Description

The TFmini Plus is a compact, single-point Time-of-Flight (ToF) LiDAR module from Benewake, designed for precision distance measurement in drone altitude hold, robotics, and industrial automation. As an upgraded version of the original TFmini, it adds an IP65-rated enclosure, improved accuracy, and optimized compensation algorithms while retaining the low cost, small size, and low power consumption that made the original popular . The module measures from 0.1m to 12m against a 90% reflectivity target, with ±5cm accuracy from 0.1–5m and ±1% accuracy from 5–12m . It supports UART, I²C, and I/O interfaces (switchable via commands), with a UART frame rate adjustable from 1Hz to 1000Hz .

The TFmini Plus weighs approximately 12g and consumes 550mW in normal operation, with a low-power mode under 100mW . Its 3.6° field of view provides directional measurement with minimal off-axis interference. The module is widely used with open-source flight controllers: PX4 supports the TFmini series via UART, and ArduPilot documentation provides parameter configurations for altitude hold and obstacle avoidance . It is suitable for individual makers building drone and robotics projects, and for business purchasers seeking a cost-effective LiDAR for volume integration.
