- Main unit is “μT”.
- Pushing Change Scale Button changes range of measuring.
- Sensitivity of sensor.
- Sound On/Off.
- Vibrator On/Off.
- Measuring range or value may differ depends on sensor on device.
- It may cause of damaging sensor or device that device is in over ranged magnetic field.
This app measures magnetic field value using the built-in magnetic sensor that is built into your device. The magnetic field level(EMF) in nature is about 49μT(micro tesla) or 490mG(milli gauss); 1μT = 10mG.
If there is any metal in the area, the strength of the magnetic field should increase. Sometimes, this app used to find electrical wires in walls (like a stud finder) and iron pipes in the ground.
Usage is simple: Open this app on your device, and move it around. The magnetic field level will constantly fluctuate. That's it!
A lot of ghost hunters had downloaded this app, and they had experimented as a ghost detector.
The accuracy depends entirely on the sensor in your device. Note that the magnetic sensor is affected by electronic equipment (TV, PC, etc.) due to electromagnetic waves.
If this app does not work properly, it may mean that your phone's sensors are damaged, broken or non-existent. To initialize the sensors, point your phone up towards the sky and move it in a figure 8 pattern. Especially, a view cover with a magnet or a leather case with a magnetic snap can cause unwanted results.
Lastly, this app cannot detect gold, silver and coins made by copper. (They are classified as Non-ferrous that has no magnetic field.)

- Gyroscope Sensor
Gyroscope sensor can measure six directions at a time. You will be able to see the effects immediately by rotating your phone slightly. Now Gyroscope sensor is mostly used in 3D game development, and possibly indoor navigation in future.
- Light Sensor
Light sensor is applied to detect the light intensity of the environment, and then adjusts screen brightness and determines whether to turn off the keyboard light. Test the effect by putting your phone in dark place and retrieving it.
- Orientation Sensor
Orientation sensor is applied to detect direction status of the device, i.e. auto rotate screen when device is rotated horizontally. It can also be used as measure equipment like Spirit Level.
- Proximity Sensor
Proximity sensor measures the distance between two objects, usually the device screen and our hands/face etc. Test the effect by moving your hand forward and backward in front of the device in Sensor Box for Android.
- Temperature Sensor
Temperature sensor provides information about your device temperature, thus you can take action when the temp is too low or high.
- Accelerometer Sensor
Accelerometer sensor is applied to detect device directions, i.e. auto rotate screen when the device is rotated vertically. It is also widely used in game development.
Sound detects the sound intensity around you and provides you detailed information about the intensity changes.
- Magnetic Field
Magnetic Field is used in many areas like metal detection and compass, which bring us lot convenience in our life.
Pressure is used to detect environmental pressure, thus to forecast weather and temperature.
Sensor Box for Android only detects changes. It may not show the correct temperature, proximity, light and pressure values if no changes occur.
For better performances, sensors are usually used together. Check out the live demonstration inside the application! Any feedback the email address below is the best way to get in touch with us.
of the magnetic field. So it is a simple magnetometer and can be used whereever magnetic fields
or the knowledge of the strength of a magnetic field is important.
1. Earth magnetic field: In the absence of any other magnetic field the strength of the Earth magnetic
field is shown. It is about 50 µT or less.
2. Compass: Certainly the Earth magnetic field can be used as a compass. The direction of the magnetic
field in the x/y plane (device in horizontal position) is visualized by a vector which in this case points to
north. As the absolute values are shown at the same time it is more easy to figure out if the direction shown
is really north or if nearby magnetic fields disturb the device.
3. Metal detector (iron, cobalt, nickel): This app can be used to detect metal. Especially iron is magnetic and changes the magnetic field strength if close to the device. The app can also be used to distinguish between metals.
As e.g. aluminum is non-magnetic, the magnetic field will not be influenced by it in contrast to iron. So if you
know it is metal but not if it is iron or not, this app will show you.
4. Electrical current detector: As an electrical current also generates a magnetic field the app can also be used to detect electrical currents even if they flow in non-magnetic metals like copper.
Incorrect values might be caused by the sensors of the device, not by the app!
-*- Metal detector -*- Works really well, with adjustable sensitivity. Vibrates and beeps when a metallic object is under the phone. Uses digital filter to eliminate noise. NOTE: Some metals (like aluminium) don't react to magnetic fields: this app won't detect them!
-*- Magnetic field detector -*- Shows a graph of the magnetic flux density on the X, Y and Z axis. All reading are in uT (microtesla). It also show the total magnetic flux density (R, white) and compares it to the earth magnetic field (30 uT, magenta).

The top number is the highest reading of the three axis'.
The three bar graphs show each axis separately. A green graph means the reading is positive (+) and a red graph means the reading is negative (-).
The program defaults to AutoRange when started and will select a range for the bar graphs based on the axis with the highest reading.
One of five manual ranges can also be selected. Selecting a low range and effectively "overloading" the bar graphs will not cause damage to your phone.
Accuracy of this software will vary from device to device and is not guaranteed. This software is intended for entertainment purposes only and not intended for use as a replacement for calibrated scientific instrumentation.

Metal Sniffer is a portable metal detector. By detecting nearby electromagnetic fields using the phone's built-in magnetometer/compass, you can locate nearby metal and magnets. You can also use it to find metallic studs and wiring behind walls. Depending on your phone, you can use it to detect metals up to 30cm away, and magnets from far, far away! Note that household equipment like TVs, and computers or even your phone case can affect readings.
Readings are separated per dimension, and is given in the unit of your choice (Tesla, Gauss, or Gamma), and combined to give a scalar reading. You can set a threshold at which the phone will vibrate when a critical reading has been reached.
You can also see a reading trend through the graph, or switch to the compass mode to find the direction at which the current is coming from! You can also record the readings to a .csv file for tracking or research.
===How to use this app?===
Very simple, just move the app around and read the measurements, if the magnetic field readings go over a critical level, the phone will vibrate, meaning a ferromagnetic material is nearby.
If the readings aren't getting updated, make sure your phone is equipped with a magnetometer.
If the readings seems to be off, it means that your sensors needs to be re-calibrated, click the re-calibration button (refresh icon) for instructions.

This plug-in for Locale and Tasker detects when you cross into or out of an area surrounding a location. Set up a perimeter around your house or work, and you can trigger actions when you arrive or leave, or even change set phone settings while you are NOT at a location. For instance, you can set up one profile to send a text to your wife when you leave work, and another profile to set your ringtone to your favorite song while you are not at work.
If you find a bug, please email me at email@example.com, and let me know. If your email leads to the discovery of a real bug, I'll refund your purchase price.
Note: If you don't have Locale or Tasker installed, this plug-in will do you no good.
Tasker Users: To use: go to Profiles, and add a "State" condition. Within the pop-up that appears, you will see a button labeled "Plugin." Tap that, and you will see "Perimeter Detection."
Locale Users: Locale has recently begun popping up a note that this plug-in duplicates their native Location function. Unlike Locale's native Location condition, this plug-in is mostly about the act of arriving at or departing from a location, not simply being at a place; you can read more details about what makes it different below. Give this plug-in a shot, compare it to Locale's built-in Location Condition, and if you are not happy with it, I'll refund your purchase anytime.
Discuss this plug-in, or Locale in general, at https://plus.google.com/u/0/communities/103577826858095621290
Technical information below - if you are interested in how it works.
Google recently provided Android devices with a low-power way to detect arrivals and departures at places you set up. This plug-in makes use of that service to set Locale or Tasker conditions. Please note: this service from Google makes use of multiple sensors (including WiFi and GPS) to determine location. When you disable these sensors, precise location becomes more challenging. Google Play Services are very good at determining location with whatever sensors it can, but bear in mind that if you disable WiFi and GPS, location will likely be in-precise at best. If you typically leave these off, consider setting perimeters with a large radius.
There are other plug-ins that use the same service to provide "geofence" detection. I believe mine is unique, though, in that I have written algorithms to prevent (or at least severely minimize) random (& inaccurate) "Exit" occurrences, which can occur with low-power geofences. My algorithm only kicks in when the Google Play Service detects an Exit transition, so it also minimizes power consumption.
Another problem some similar apps have is that the geofences you set up don't always work after a restart. This plug-in does not suffer that problem, nor will geofences remain in use after you've stopped using them.
What makes this different from Locale's built-in Location Condition?
Perimeter Detection is not simply about "where you are", but about entry and exit. Say you've set up a "Disable Bluetooth while I am home" type condition - then say you manually enabled BT while you are at home. Sooner or later, you will find that BT has been disabled again, because Locale detects that you are at home. With perimeter detection, you set up a "Disable BT when I arrive home" condition, and once you are at home, if you enable BT, it will stay on - because the plug-in recognizes that you aren't continually "arriving" home, you simply are STILL at home.
Change your device to a motion detector, or remote surveillance camera or even spy cam with motion detection functionality, you can also detect motion for other apps such as Tasker or Automagic
Program uses device's built-in camera so effects can be unsatisfying, reaction time depends on device performance and frame size, maximum and minimum size of recorded frames depends on the device.
