Tips with airspeed sensors. 1. The digital ones don’t care which tube is which as they just measure the differential. The analog ones, as Andrew said, do care and you need to get it right. 2. Make sure when you mount the pitot tube, that the holes in the side are well clear of the airframe and not blocked. These are the static ports and need to be in static air. Turbulence upsets them. 3. You should be able to connect the digital ones to one of the two I2C ports. The other one should be the compass that comes with the GPS. 4. These should work on Pixhawks or at least the cheap clones I use. Just connect them to the 6.6V analog input or the half voltage to the 3.3V. 5. Pitot tubes NEED to in clean air otherwise you are wasting your time. Keep them on the nose or on a bracket well above the airframe or wing. 6. Arduplane very very definitely uses airspeed. So much so, that an airspeed sensor is almost mandatory on Arduplane and I won’t fly a valuable drone without one. Especially for autoland or reliably flying lawnmower mapping patterns. Ones without it can stall and spin in on turning to the upwind legs in strong winds - ask me how I know☹️
@Ironiic zero being that i2c is a parallel digital bus, all peripherals can be on the same port...Quite frankly I can't see the need for 2 ports, as each can address up to 256 devices.
Unless your fuselage is sealed, there is no need to use two fuel lines. The static pressure port (bottom one) can be left open, and placed inside the fuselage with a piece of open cell foam tie-wrapped around it. Just put it inside the fuselage such that it is out of any airflow. This will work just as well, if not better than measuring the static pressure at the pitot, since turbulence could easily effect it out there and inside the fuse is very well protected from same.
in iNav 2.2.1 you can use the airspeed for the Logic Conditions in the Mixer tab. I plan to apply airspeed conditional rules to deploy flaps for me....currently my plane with this sensor has other issues though.
Does anyone know the diameter of the hole that's on the black plastic part of the pitot tube? The one that's near to the part where you connect the pitot with the pipes, thank you.
That little 7002 is 60 % the cost of the H743-WING V2 FC dang ! ? I guess they get you on peripherals $$ or maybe Zuckerberg has been showing them the way 0_o Good work Newt ! love your stuff.
@@AndrewNewton I just fount that out today. 103.00 for FC and 130.00 for speed kit ugh ( Guess they say don't fly this FC with out the speed kit as its not GPS speed only corrected like Inav ? must use both? My poor brain ! lol Thanks for helping the masses learn btw!
If INAV doesn't use the airspeed sensor then how does it determine the correct flying speed when doing return to home etc? If it is just using ground speed and it is a windy day it could have real problems with stalling when flying down wind couldn't it?
It's not even using ground speed. iNav uses a preset throttle position and adjusts throttle to maintain altitude. Yes stalling is a problem if you dont have the cruise throttle set high enough.
Just about to take the leap into inav to replace my ET Vector as it is no longer supported (even though I love it)... I know this video was a year ago but airspeed is one of my must haves because I’m so paranoid about stalling when flying long range (especially on a wing style plane). Anybody know if inav can use the airspeed now to maintain minimum airspeed and manage throttle for Loiter and RTH yet?
@@@AndrewNewton mate now that's funny lol...but I think you would need the camera pointing at you to see yourself and hopefully someone else driving while you're at it🤣🤣✌
ruclips.net/video/x1_WHJfG7UE/видео.html Was suss for a while but GT's 7" Tyro clip made me realise the other night & this clip has confirmed it for me..... Grumpy Trev & UAVFutures fly from the other end of this park! lol! Any chance we'll see yourself, GT, Stu & the boys getting together for a fly-together some time??? :D All the best....

Essential information again, many thanks Stephen
The other i2c port doesn't have to be used for a compass, it can be used for any other compatible i2c device such as OLED, temperature sensors etc

@@jamesellis5445 Many I2C devices are not able to have their addresses changed. Two ports allow you to have two devices with the same address.

Again Thank You Sir Andrew for a well explained hardware setup! Keep it up sir! Kudos to you sir and stay safe!
Thanks, will do!
Awesome video 👍.
Air speed is major factor for long range and efficient flight. This sensor is not a gadget, it works.

Oh yes. I'll have to investigate
@@AndrewNewton Check this out for LCs and flaps ruclips.net/video/yJCHlc2xohY/видео.html

Just set mine up - seems to work when I blow on it - only issue it it thinks we're doing 143mph at rest! Will look into.
UPDATE! All I needed to do was take the model outside and show it some satellites. Seems to have calbrated itself!
Excellent. It fixed itself.

This one isn't even available anymore, have to get the digital version.

With INAV the airspeed sensor is not used for flight control, only displaying the value.
Does this work with radiomaster expresslrs also?
It works with INAV or Ardupilot flight control boards. The RC protocol is not really related.
I think it is a pitot-static pressure sensor for measuring the velocity of our aircraft. Am I correct sir
Correct.
What is the maximum speed it can detect?
I'd have to look it up in the specs, but you can do that and let me know.
If INAV doesn't use the airspeed sensor then how does it determine the correct flying speed when doing return to home etc? If it is just using ground speed and it is a windy day it could have real problems with stalling when flying down wind couldn't it?

I think yes, but best to ask on the INAV FW Facebook Group.
Will the F765-WING board do RTH without the air speed sensor, or does it use the air speed to control flight.??
iNav uses GPS for RTH. Air Speed sensor can't be used for any control, just information
@@AndrewNewton Thanks Andrew.
How do you connect to a omnibus f4 pro v3 board using arduplane
Cant help with that sorry
Is the arrow in the center of the screen the wind direction.
No indicate to home location
The arrow points to home i.e. where Andrew is.
Will this work worth all radio systems, I have a horus x12s, what's needed to communicate
Connects to a Matek flight control board. Independent of radio system
I have a furious fpv sensor. Do I need the board
More information?
What is the use of airspeed sensor?
It measures air speed, rather than ground speed like a GPS or speed gun. I guess you could see the stall speed of the wing.
Hey can you plz provide us a code for this sensor
Discontinued unfortunately
Hello, can you share the code you are using?
INAV on the board
Hi !
Does this sensor work with matek f405- wing ?
Yes, did you miss that in the video?
It's included in the list at 1:22, so I guess yes
Yeah I missed it
Thanks !
You should strap it on top of your car and do a proper test, see if it breaks the 100 MPH mark!
@Mark Harrison lol maybe 60 MPH...Andrew's state (Victoria) has a 100 KPH speed limit...If he goes north of the border, he can stretch it to 110 KPH.
@@jamesellis5445 We do have some 110kph freeways, I can see myself hanging out the window with FPV goggles on

Yes, I always thought they were in Melbourne until Stewie was at the ovals one day.
