We are releasing a new airspeed prototype, we know the hardware might be good, we just need to test more under ArduPlane (only supported on 3.8). Recommendations or any issues with this sensor are welcomed! If you are interested in becoming a beta tester please ping me.

Cool, follow results I didn’t buy airspeed to my new proyect yet, 
I have ordered one - despite the shipping costs to Europe.
Rolf, thanks for your order. How much you paid?
With lowest shipping cost ($15.50) i will have to pay german tax (19%) on the total costs.
Looking at the datasheet it seems like a good sensor! How are your tests with them going? Do you have test data? The company I work for is looking for a new Airspeed sensor to follow the change to Pixhawk2, and this seems like a nice option. If it goes well, we plan to buy a batch this month.
It has been working well. We have sold a few of them and no complains so far. =)
Sorry to hear that. Please, next time let me know so we can work out a better price by quoting shipping manually and also give you other trade options.
Warmly,
Thanks Jordi,
the MS5525 arrived today (German customs took 14 days to calculate € 9.86 and to fill in a large form - 
). The sensor and pitot tube will be installed in our VTOL. I will report.
Best regards
Rolf
Thanks for sharing your results! Awesome. I’m releasing more sensors soon, new magnetometer as well. Please let me know if you are interested. Please PM for developer/tester discount.
I just received the new MS5525 airspeed sensor and so far I can’t get it to work on the 2.1. I’m running 3.8rc5 and have set the TYPE to 3 and Bus to 1. The airspeed is stuck on 39 and altitude is on zero. When I blow on the pitot tube there is no change. I have two of the MS5525 and they both do the same thing so there’s something I’m missing. Any ideas? Also I get a Airspeed Sensor un-healty message on start-up.
Is ARSPD_PIN set correct ? ARSPD_PIN = 65 for Pixhawk 1
No idea if this is identical for 2.1
Hi Rolf, Yes, The ARSPD_PIN is Set to 65
I was just looking at the Libraries and the airspeed library has the driver for the MS5525 airspeed sensor but the Baro library doesn’t have a driver for the MS5525. It’s been a very long time since I was working with the development but I think that is why I’m seeing airspeed but no altitude.
Shotfire,
I recommend not blowing with your mouth the sensor, we noticed is very sensible to humidity. You can press the inlet with your finger and you will see good airspeed indication or use a fan/blower.
Warmly,
HI
What do we do if we have high humidity in our area? will it work?
HI Jordi,
Are you planning to add compass and magnetometer sensors inside the same airspeed board?
Could you get it to work? We are having the same problem. Changed both settings but no airspeed reading
I have the same problem, couldn’t get my existing airspeed sensor to work with Pixhawk 2, so just tried the new MS5525 today, can’t seem to get any readings at all, have the ARSPD_TYPE = 3 and ARSPD_BUS = 1. I am connecting to the I2C 2 port on the Pixhawk 2, and I’m running 3.8.0 beta6.
Has anyone successfully got an airspeed sensor working with the Pixhawk 2 yet?
