TeraRanger 测距仪
TeraRanger provide a number of lightweight distance measurement sensor based on infrared Time-of-Flight (ToF) technology. 他们通常比声纳更快、范围更大、比基于激光的系统更小、更轻。
PX4 supports:
- TeraRanger Evo 60m (0.5 – 60 m)
- TeraRanger Evo 600Hz (0.75 - 8 m)
:::info PX4 also supports TeraRanger One (I2C adapter required). This has been discontinued. :::

布线
All TeraRanger sensors must be connected via the I2C bus.
软件配置
The sensors are enabled using the parameter SENS_EN_TRANGER (you can set the type of sensor or that PX4 should auto-detect the type).
:::info If using auto-detect for Evo sensors the minimum and maximum values for the range are set to the lowest and highest possible readings across the Evo family (currently 0.5 - 60 m). In order to use the correct max/min values the appropriate model of the Evo sensor should be set in the parameter (instead of using autodetect). :::
:::tip
The driver for this rangefinder is usually present in firmware. If missing, you would also need to add the driver (distance_sensor/teraranger) to the board configuration.
