Support for this sensor was added to Rover-3.4.
Connecting and Configuring¶
The ECT400 provides distance measurements using the NMEA protocol over serial at 115200 baud.
The sensor can be connected to any available serial/uart port on the fligth controller. In the diagram below the sensor is connected to SERIAL2.
If the SERIAL2 is used then the following parameters should be set:
Then the following range finder related parameters should be set:
- RNGFND_TYPE = 17 (NMEA)
- RNGFND_MIN_CM = 13
- RNGFND_MAX_CM = 10000 (i.e. 100m). This is the distance in centimeters that the rangefinder can reliably read.
Testing the sensor¶
Distances read by the sensor can be seen in the Mission Planner’s Flight Data screen’s Status tab. Look closely for “sonarrange”.
