WeatherSignal - Sensor Toolkit

WeatherSignal lets you monitor all the sensors on your device, turning your phone into a tricorder, or mobile science kit. Particularly powerful for users of the Galaxy S4, but working on 1000's of devices - see what your phone can do!

This app is 100% ad-free :)

*Thermometer readings are experimental!*

The app makes use of native phone sensors to display local atmospheric readings, which are then displayed on our live-updating weather map. By using WeatherSignal you are becoming a part of the most ambitious weather crowdsourcing project in the world – helping to record weather patterns on a more localised level than ever before.

Features:

✓ Readout for all the sensors on your device (think Tricorder - but real!)

✓ Widgets for temperature, magnetic, light, humidity and pressure sensors (if you have them)

✓ Save all data to CSV on your SD card - play with it however you like

✓ Map of readings of other users and of your own, see averages within each map window, click on icons to see full readout

✓ Manual reports

✓ Tonnes of graphs (for geeks like us :))

✓ Contribute to our maps (you can turn off sharing in settings)

*** This app is experimental! Readings from sensors may be faulty, we are developing ways of filtering and correcting this. In particular, individual TEMPERATURE readings may be incorrect, but when averaged over many users we get reliable information for our community powered maps. ***

Android phones are increasingly being equipped with a sophisticated array of sensors and the WeatherSignal app is designed to help you make use of them. What the app can display depends on what model of phone you have and how many sensors it has. The app works best on the Galaxy S4 (as that phone has the most sensors) but has functionality on most Android devices.

The WeatherSignal app can measure:

✓ Pressure (certain devices only)

✓ Temperature (see note below)

✓ Light Intensity

✓ Humidity (Galaxy S4 only)

✓ Magnetic Flux

✓ Acceleration (you'll need to turn this on in the application settings)

You can see graphs of all these values live or over time.

This app is also one of the first to feature Google's Activity Recognition: monitor when you're walking, in vehicle, on a bicycle. You can save the results to CSV and perform your own analysis, for example for quantified self tracking

*** NOTE ON TEMPERATURE READINGS ***

We’ve come up with an algorithm that can translate battery temperature into ambient temperature. For each user this can sometimes be a bit approximate but we've discovered that there is a very strong correlation between battery and ambient temperature when spread over a crowd of users. If you are using a cell phone without an external thermometer then the temperature reading you’ll see is a battery temperature reading converted through our algorithm. Often the algorithm will get it wrong, however we've shown in a research project with meteorologists, that with appropriate averaging and filtering, these readings correlate extremely well with external ambient air temperature.

The Galaxy S4 which has an ambient air temperature may also produce incorrect readings - if the phone is hot (perhaps because it's been in your pocket or has been charging or intensively used) then the readings will be higher than the ambient environmental air temperature.

You might also be searching for: lux meter, lightmeter, light meter, magnetometer, hygrometer, accelerometer, thermometer ... if your phone has it, WeatherSignal reads it, graphs it, saves it.

(weather signal, opensignal, open signal)WeatherSignal让您监控您的设备上所有的传感器，把你的手机变成一个的的tricorder，或移动科学套件。特别是强大的Galaxy S4的用户，但1000的设备上工作 - 看你的手机可以做什么！

这个程序是100％无广告:)

*温度计读数实验！

该应用程序，使得使用手机自带的传感器显示当地的大气读数，然后将这些实时更新的天气地图上显示。通过使用WeatherSignal成为天气众包的最雄心勃勃的项目在世界上的一部分 - 记录天气模式上比以往更多的本地化水平。

特点：

✓您的设备上的所有传感器读数（认为的tricorder - 但真实的！）

✓小部件的温度，磁，光，湿度和压力传感器（如果有的话）

✓你的SD卡上所有数据保存为CSV - 用它玩你喜欢的

✓地图的其他用户和自己的读数，平均每个地图窗口内，点击图标看到完整读出

✓手动报告

✓吨的图表（像我们一样:)怪才）

✓贡献给我们的地图（你可以在设置中关闭共享）

***这个程序是实验！从传感器的读数可能出现故障，我们正在开发过滤和纠正这种方式。特别是个别的温度读数可能是不正确的，但在许多用户，我们得到可靠的信息，为我们的社区供电地图平均时。 ***

Android手机正越来越多地配备了一个复杂的阵列传感器和的WeatherSignal应用程序旨在帮助你利用它们。应用程序可以显示取决于您拥有的手机是什么型号的，它有多少传感器。该应用程序最好在S4（银河，手机拥有大多数传感器），但大多数Android设备上的功能。

可以测量的WeatherSignal应用程序：

✓压力（仅适用于某些设备）

✓温度（见下文附注）

✓光强

✓湿度（仅银河S4）

✓磁

✓加速（你需要打开这个应用程序设置）

你可以看到所有现场或随着时间的推移，这些值的图表。

这个应用程序还首次采用谷歌的活动识别：监视，当你行走，车辆，自行车上。您可以将结果保存为CSV和执行自己的分析，例如，用于量化自我跟踪

***注意温度读数***

我们已经想出了一个算法，它可以翻译电池温度环境温度。对于每个用户，这有时可以是一个有点近似，但我们发现，有一个非常强劲的电池和环境温度之间的关系时，一大群用户遍布。如果您正在使用手机，无需外部温度计，那么你会看到温度读数是电池的温度读数，通过我们的算法转换。通常情况下，算法会得到它的错误，但是我们已经证明在一个研究项目中的气象学家，与相应的平均和滤波，这些读数极其相关以及与外部环境的空气温度。

其中有一个周围空气温度的Galaxy S4也可能产生不正确的读数 - 如果手机正在热销的（也许是因为它一直在你的口袋里，或已被充电或密集使用），然后读数将高于周围环境的空气温度。
