hello. i am using pixhavk cube. i want to integrate a sensor to avoid collision with objects on my drone when flying outside. is there anyone who can help me with this? which sensor would be better to buy and how can i solve the installation?
Collision Avoidance Sensors for Pixhawk
If you’re using a Pixhawk flight controller and want to integrate sensors for collision avoidance during outdoor flights, here’s how you can proceed:
Best Sensors for Collision Avoidance:
- LightWare LiDAR:
Models: LW20, SF11/C
Highly accurate sensors suitable for long-range object detection and altitude measurements.
Advantages: High resolution, ideal for high-altitude flights.
Usage: Object detection and ground altitude monitoring.
- Ultrasonic Sensors (Sonar):
Models: Maxbotix MB1240, MB1260
Effective for detecting nearby objects.
Advantages: Affordable and easy to install.
Limitations: Limited range and sensitivity to noise.
- Intel RealSense Depth Cameras:
Models: D435, D455
Provides 3D mapping and depth analysis.
Advantages: High precision for various applications.
Limitations: Requires higher computational resources.
- Radar Sensors:
Model: Benewake TF03
Suitable for long-range detection (up to 100 meters).
Advantages: Performs well in all lighting conditions.
Steps to Install the Sensors:
- Hardware Installation:
Mount the sensor on the drone (usually at the front or bottom).
Use vibration dampers to stabilize the sensor.
- Electrical Connection:
Connect the sensor to the appropriate port (e.g., UART, I2C, or PWM).
Ensure the sensor’s voltage is compatible with the Pixhawk.
- Software Configuration:
Use Mission Planner or QGroundControl:
Configure sensor-specific parameters (e.g., RNGFND1_TYPE for LiDAR).
Enable Obstacle Avoidance by setting the parameter AVOID_ENABLE to 1.
- Testing and Calibration:
Test the drone in an open area.
Verify the sensor data to ensure the collision avoidance system functions correctly.

@elshad if you want to avoid collision with objects outdoors when flying in position mode, I would leverage the Lightware SF45
