- You can calibrate it (many devices doesn´t provide measurements in any standard unit).
- It shows you maximun,minimum and average measures.
- Units: lux (but you can use other units introducing a multiplication factor).
It will only show measures in compatible devices.
IMPORTANT! ABOUT RESOLUTION OF MEASURES:
Because of the resolution of the light sensor of some devices like Samsung Galaxy S2, in some devices the app will only give measures with a resolution of 10^n lux ( 10 lux, 100 lux, 1.000 lux...) or other kind of scale. It´s not a bug of the app, it´s due to the resolution of the sensor of these devices.
You should also keep in mind that this software shows the measures given by the device and so, if the device sensor doesn´t give good quality measures (it happens in some devices), this software won´t either give good quality measures. Please do not vote negative in that cases.
It is proved by several studies that different light colors have different impacts on the human mood.
You have the choice between Relax, Excite, Creative or Concentrate.
Use in the dark!
Now with timer!
This plug-in is highly customizable:
-choose your light intensity value in a set of 8 predefined ones like full night, .. or sun day
-display the current light level
-choose a custom light intensity value
-choose the threshold to be “below” or “above”
-set up the minimum duration of the condition that will trigger the event
Google Play shows this app only to users who have a light sensor in their device. (If you are allowed to buy this app, then you have a light sensor.)
This Locale plug-in is from the same developper as:
-Locale/Tasker Ping Plug-in
-Locale/Tasker Light Sensor Plug-in
-Locale/Tasker Screen On Plug-in
-Locale/Tasker Screen Off Plug-in
-Locale/Tasker Proximity Sensor Plug-in
-Locale/Tasker Proximity Click Plug-in
This is not a standalone app. It requires Locale by TWO FORTY FOUR A.M. LLC or Tasker by CRAFTY APPS to work.
For Tasker users: Once installed, you will find this plug-in under the "State/plug-in" category, not under the "Event/plug-in" one.
Test the brightness/intensity of light sources using your phone light sensor. Use the light sensor to investigate the inverse-square law from a point source of light, true magnitudes of light bulbs (as our eyes do not directly perceive comparative brightness accurately due to the constriction and retraction of the pupil), solar intensity variations dependent upon weather, and the ability of objects and surfaces to absorb, reflect, and/or transmit light.
A csv file is created and modified on the phone's internal memory.

This app requires devices with a light sensor. It uses native light sensor data acquisition that gives accurate and instant light intensity reading. This type of native data acquisition is available for many supported devices.
Other devices are also supported by the built-in compatibility mode but the accuracy and the speed of light intensity reading may be limited and custom calibration is required for correct reading under compatibility mode.
Custom calibration procedures are described on the following page:
Also, on some devices the light sensor may not be linear, not continuous and measuring errors will occur or the maximum measuring range may be limited. This is not app's fault.
This app also provides a light color temperature measurement in K (degrees Kelvin) that is only supported on devices employing color light sensor. On all other devices the display shows n/a (not available).
Sensor Kinetics is an advanced viewer and monitor for all of the standard sensors available in your Android device. The new built-in Multi-Sensor Recorder allows you to record up to six kinetic sensors simultaneously.
Written by one of the pioneers of the use of accelerometers and gyroscopes within the modern smartphone, it provides a comprehensive look at the total dynamics of the combined operations of all the sensors.
The app demonstrates the use of the accelerometer, gyroscope and the rotation sensor to control a tilt based view navigation like the RotoView technology by INNOVENTIONS. It also demonstrates the operation of the magnetic sensor, the linear acceleration sensor and the gravity sensor within special graphical displays.
Use Sensor Kinetics to monitor and understand the behavior of the sensors while you change the delay setting or activate/deactivate specific sensors. Each sensor is attached to a sophisticated chart viewer. The Multi-Sensor Recorder records multiple sensors simultaneously at a controlled data rate. If you need to save or share sensor charts, please purchase the companion Sensor Kinetics Pro.
For educational users, the app includes comprehensive help files which provide physics students with hands-on knowledge of how these sensors interact with smartphones and suggest numerous experiments you can perform on your phone or tablet.
Who Should Use Sensor Kinetics?
Developers, students, hobbyists, technicians, engineers... anyone who's curious about what lies "under the hood" of their mobile device!
Test your Android phone or tablet: Sensor Kinetics allows you to test all of the sensors on your device. For example, you can quickly determine if your Android device has a gyroscope sensor and how fast it's operating. The numerous chart viewers allow you to measure any sensor over time and gauge their accuracy and behavior.
Educational: Sensor Kinetics demonstrates the physics of gravity, acceleration, rotation, magnetism and more as these forces are measured by your phone or tablet. The app includes comprehensive help files with easy to understand information and experiments you can perform with the sensors.
App Developers: View in detail the behavior of the sensors used in your apps. Compare the performance of advanced sensors like gyroscope, linear acceleration sensor and the rotation sensor.
This app relates to gyroscope and accelerometer data logging, magnetometer, smart scroll, science, physics, tilt measure, pressure sensor, relative humidity sensor, light sensor, linear acceleration, temperature sensor, proximity sensor, gravity sensor, MEMS, kinetics
** models like Galaxy S3-S5 or Galaxy Note2-Note4 are missing temperature and humidity sensor, not my fault, sorry, the device manufacturer has decided to remove these sensors **
** if a sensor is set as "NOT PRESENT" is because your phone doesn't have it **
- Ambient temperature in degrees celsius
- Percentage of moisture in the air
- Light intensity
- Air pressure
- Height above sea level
- widget with ambient temperature! more coming soon
** The data is read directly from the sensors could then have an error of up to 5-10% (in the worst case) that does not depend on me, but by the sensors, unfortunately I can not do anything about it, to try to reduce the errors Please keep the device on a flat surface for a few seconds, so that the values are optimized, if your hands touch the device, the temperature will be too high of some degree **
If you want to report the full compatibility of your device with the application please leave feedback or send me an email, so it will be added to the list, any feedback and comments are very much appreciated, the application aims to be simple and instant, to have at hand all the data from the main sensors of the phone, if there are suggestions, recommendations and requests for additions will be happy to provide (where possible)

New! Increased brightness in the last levels to the max available in your phone.
"To put it simply, Lux kicks the pants off of Android’s stock brightness manager, and it’s worth every cent." - Lifehacker
"Lux is a third-party app that allows you to easily calibrate your phone’s brightness sensor, saving you battery power and reducing eye strain if your phone is normally too bright in dark rooms." - HowToGeek
Lux isn't your ordinary brightness app. It intelligently adjusts the brightness of your display based on the environment you're in. If you step into a dimly lit room, Lux will automatically lower the brightness of your display to make it not only comfortable to read, but to also preserve battery power.
Lux is also able to adjust the screen temperature of your display automatically to make it appropriate for night usage. At sunset, you can have Lux automatically warm your display and switch to your Night profile. If you're an astronomer, you can enable astronomer mode to cut out harsh white light. If you have a root enabled phone, you may even be able to apply these enhancements at a low level with Lux's plug-in system.
Perhaps the best thing about Lux is that you can teach it how to behave. If the backlight is too bright or dim for your liking, simply open the provided Dashboard, adjust the brightness slider to the level you desire, then hold the link button. Lux will use this new 'link' as a reference in future.
Give it a go! I want you to test Lux for more than the 15 minute refund period offered by Google. I understand that some devices may not have the best quality light sensor, and that you may need more time to play around with settings. If you find that Lux doesn't suit you after the 15 minutes is up, you can request a refund within a week of purchase via e-mail - no questions asked.

Screebl, the battery saver keep your screen on wunderkind, works based on a simple observation: we generally hold our phones or tablets in roughly the same positions when we're using them. Screebl uses the sensors in your mobile device to detect how you're holding it, and when your device is within a configurable range, the screen is kept on. Move out of that range, and Screebl releases the lock and the screen is allowed to go off. Using gravity, screen orientation, and other cues, your screen is kept on when it should be, and turned off when you don't need it. It's simple, but it works amazingly well!
How is Screebl a battery saver? Well, it's simple. On most phones, the screen is the single largest consumer of battery power. With Screebl running you can reduce the average amount of time that your screen is on by only keeping it on when you're ACTUALLY using your phone. The amount of savings can vary significantly by device and usage patterns, but it is not uncommon for users to see savings of 20% or more. See our web site for more details.

✓ PocketLock locks your phone when you put it into your pocket, unlocks when you take it out
✓ AppExceptions let you turn Screebl off when selected apps are running in the foreground
✓ Locale Plug-ins and Tasker integration provide automated control and customization of Screebl
✓ Look-and-feel customization lets you make Screebl look the way YOU want
✓ Better detection algorithms
✓ Screen timeout set from Screebl
RECEIVE_BOOT_COMPLETED - Needed to a start Screebl when phone starts up.
INTERNET - Needed to check for new instructional videos and submit debugging information.
WAKE_LOCK - Needed to keep the screen on.
WRITE_SETTINGS - Needed to update system settings related to screen timeouts.
GET_TASKS - Needed to disable Screebl when selected apps are running (AppExclusions).
BILLING - Needed to allow in-app upgrade of Screebl Lite to Pro.
READ_PHONE_STATE - Needed to check phone state (e.g., in-call, speakerphone on, etc.) to provide in-call behavior (e.g., disable Screebl or lock screen on)
✓ Some phones do NOT deliver sensor events when the screen is off. Examples include some HTC phones, some Sony Xperia phones, and quite a few Motorola phones. PocketLock may not work properly on these phones. See this link for more info: http://www.saltwebsites.com/2012/android-accelerometers-screen-off
✓ PocketLock sometimes causes battery drain on some devices. The effect of the PocketLock feature varies widely from one device to another. The longer that you have PocketLock monitor for removal from your pocket, the more power used. Most devices see a minor increase in power consumption when using PocketLock (4-8%).
✓ Stillness detection doesn't detect small movements on some devices. A few devices have coarse-grained sensors, and movement is not detected well, causing unwanted stillness timeouts. I am working on a fix for this that will be in an upcoming release. Most phones are fine.
✓ Screebl doesn't start when the phone is powered-on. On some HTC phones the "fastboot" capability can cause problems with Screebl starting at power-on. I've done my best to fix this, but it still is a problem on some HTC devices. Screebl must NOT be moved to SD storage.
Most sensors also display a chart with the output of the sensor so you can monitor changes during the time.
You can even capture the values and export them to your computer with a csv file or view them directly in the app.
