If the phone ist not moved the displayed value fluctuates by approx. +/- 0.05 hPa which I consider surprisingly precise. If converted to altitude at elevations below 1000m amsl the fluctuations correspond to approx +/- 45cm.</P></BODY></HTML> Wed, 14 Nov 2012 11:37:52 GMT https://community.sony.com.mk/t5/xperia-archive/precision-of-pressure-sensor/m-p/3022963#M226081 msettles 2012-11-14T11:37:52Z Re: Precision of pressure sensor https://community.sony.com.mk/t5/xperia-archive/precision-of-pressure-sensor/m-p/3022964#M226082 <HTML><HEAD></HEAD><BODY><P>As you say the precision is fairly impresive.&nbsp; With a bit of filtering over the raw readings I use it to record the altitude in to 10 cm in my biking app IpBike.&nbsp; It means I can get fairly good gradient numbers when combined with an ANT+ speed sensor.&nbsp; Far better than you could get with a GPS only solution.</P></BODY></HTML> Thu, 15 Nov 2012 21:43:35 GMT https://community.sony.com.mk/t5/xperia-archive/precision-of-pressure-sensor/m-p/3022964#M226082 Ifor 2012-11-15T21:43:35Z
