Connecting the Sonar Sensor on APM 2.x

The sensor’s GND, V+ and “AN” or “3” pins should be connected to APM 2’s A0 pins as shown in the diagram below:





Connecting the Sonar Sensor on PX4

You will need to assign the Sonar (signal line) to an appropriate PX4 pin in Apm Planner – Configuration – Advanced Params – Adv Parameter List using the SONAR_PIN parameter. The following PX4 “Pins” are available for SONAR use.

SONAR_PIN = 11 – (recommended)
The “airspeed” pin. Located on a 3 pin DF13 connector on the PX4IO
board, but directly visible to the ADC on the PX4FMU. This pin can
take voltages up to 6.6V (it has an internal voltage divider).

SONAR_PIN = 12
A general analog input pin. Located on pin 3 of the “FMUSPI” port on the PX4IO board, this pin is directly visible to the PX4FMU analog input code. This can take voltages up to 3.3V.

SONAR_PIN = 13
A general analog input pin. Located on pin 4 of the “FMUSPI” port on the PX4IO board, this pin is directly visible to the PX4FMU analog input code. This can take voltages up to 3.3V. It is being worked on and will be included in this section when it is available.

Mounting the Sonar Sensor



Enabling the Sonar through Apm Planner

Enable the sonar by connecting your APM/PX4 to the Apm Planner and then:
• Go to Initial Setup > Optional Hardware > Sonar
• Check the “Enable” checkbox
• Select the sonar model from the drop down list
