TeraRanger Rangefinders
TeraRanger provide a number of lightweight distance measurement sensor based on infrared Time-of-Flight (ToF) technology. They are typically faster and have greater range than sonar, and smaller and lighter than laser-based systems.
PX4 supports:
- TeraRanger Evo 60m (0.5 – 60 m)
- TeraRanger Evo 600Hz (0.75 - 8 m)
PX4 also supports TeraRanger One (I2C adapter required). This has been discontinued.

针脚定义
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.
