Re: Barometer MS5611 accuracy improvement

Finally after some more tests I have to say that the improvement is basically for the temp measurements. Above 20ºC The noisy readings from the pressure sensor mask the accuracy improvements. So although there is a more precise reading, it does not seem to affect the final pressure value. However un...

Actually I was testing the sensor for my own purposes. I don't have a multiwii device ready to test (yet). However as I noticed that the Multiwii code is using the calculations provided by the specs I decided to post here as you could benefit from the improvements. I am attaching here a patch of Sen...

Barometer MS5611 accuracy improvement

I was just playing around with my MS5611 sensor and in the specs I found room for improvement in the pressure and temperature calculations. The specs of my MS5611-01BA03 from measurement specialities says the following: At OSR 4096 the ADC gives an accuracy of 0.012 mbar At OSR 4096 the ADC gives an...
