This article is about pressureNET, which is my open source Android app that collects atmospheric pressure readings from sensors in phones and tablets. I'm happy to answer questions as always :).
Edit: You can browse a visualization of our collected data from last year at http://pndv.cumulonimbus.ca http://pndv.cumulonimbus.ca to get an immediate overview of our quantity and quality of data.
- sudont 14y agoWhat do you think of adding iOS devices into the network once BLE sensors become more common? http://mosoro.com/labs-hardware-enviro.php http://mosoro.com/labs-hardware-enviro.php
- cryptoz 14y agoAbsolutely! I hadn't heard of Mosoro before; that Enviro product looks very, very cool. We actually plan on building an iOS client very soon anyway, in order to gain greater visibility (and also to learn how to build iOS apps). So far, there is little to do inside pressureNET if you don't have a pressure sensor, so we've held off so far.
- cameldrv 14y agoCan you tell us more about how you post-process the data? Given that you're looking for small differences from what the nearest ASOS is reporting, compensating for altitude and sensor calibration seems like a big challenge.
- cryptoz 14y agoAt the moment we are not doing any post-processing. Our current approach is to work with researchers at universities who specialize in the calibration of pressure sensors like ours. We're talking with Cliff Mass at the University of Washington, and as soon as we put out a new update to pressureNET with privacy controls for our users, we will be streaming our data live to Cliff (and other researchers who are interested). This is our primary short-term goal, as it's the major hurdle we must overcome before pressureNET is a truly useful product.
- aw3c2 14y agoplease please if you give users the control, please let them also allow completely free and open sharing. that way random interested hackers can play with the data for random weekend projects and the like.
- cryptoz 14y agoDefinitely! This project has the potentially to be immensely beneficial to humanity, but only if it's open. So our code is open. But so far we've struggled to make the data open out of privacy concerns, so we're not totally open yet. But open sharing of data is absolutely critical. So yes, it'll be done, and done ASAP as well. We're hoping to have that update out next week.
- kposehn 14y agoCompletely awesome. Sent you an email - we have some tools that might help :)
- miahi 14y agoI had your application installed for a while on my Galaxy Note, but it drained the battery so I had to uninstall it. Just downloaded it again to check if it still has issues.
- cryptoz 14y agoWe had battery issues until December, and everything should be fixed now. Thanks for downloading again and I hope it's better this time.
