I have a fuel sensor (documentation below) that has a PWM output between 1100 us (when the tank is empty) to 1900 us (when the tank is full). We are creating a UAV prototype using a PixHawk as our flight controller, but I am unsure how to integrate this fuel sensor and send the data to the GCS. Any insight would be appreciated. Ideally, we do not wish to alter the code extensively, but are open to any options (I2C etc). We would be using 2 of these fuel sensors as we have 2 separate hybrids we are using for our drone.
Is there anyone in the community that has experience with using fuel level sensors that can be of assistance?
