Lol this might be a dumb question but ive been lookin around and no answer... my logic tells me its the same thing but my curiosity keeps askin is there any difference? soo with that said is there any difference?

What is the difference?
G-sensor is a gyroscope, in other words an orientation sensor.
motion sensor is more accurate, it MAY or MAY not have G-sensor's capability, this depends on the software implementation. but the hardware itself is capable of detecting and reacting to all kinds of movement.
G-sensor needs _relatively_ sudden movements to activate the gyroscope (think of a marble in box), if the phones (the box) is in landscape, and you tilt it to portrait, the gryo detects it (ie marble rolls to one side). However, if you keep the phone/box's orientation the same, and move the phone closer or further from you (assumign you ar eholding the phone): now if you move it slowly, the marbles won't roll, this is g-sensor. becaue it can't detect this movement. but if you suddenly jerk the phone/box, even if the orientation is the same, the g-sensor should detect it (ie the marble will move). ummm.. just like those dice games on iphone/itouch (if you 've seen the latest itouch commercial).
motion sensor detects all kinds of movements, it's only up to the software to decide if all functionalities are implented or only "up till" the G-sensor capabilities are implemented or something else. best example, G1's compass view, slow movement with the phone in the same orientation will pan around the map.
that being said even the motion sensor has its limits, if you move the phone uber slowly, i bet it won't detect the motion, unless it's military grade (read: 007 gadget ), if that's the case, then i don't think the phone would be $179 either

in other words motion sensor is better than the g sensor n that is super crack juice i was a lil worried there cause i thought g sensor would be better for some reason but thanks alot now i know something i didnt... thanks =)
In general, these are the same thing. They use a part called an Accelerometer, which measures acceleration, or the forces exerted on a mass within a chip. The force of gravity pulls it in a certain direction with 1G of force, so that's how things like the iphone can detect what orientation it's in, by looking for which direction gravity is.
By shaking the device or moving it, you also exert forces on the mass inside, and cause it to register different forces in different directions, which are reported to the OS in 3 axis.
Notebooks use the same tech to know when to park the heads. If the accelerometer suddenly sees that there is no gravity anymore, it assumes that it is moving towards the ground and will then park the heads of the drive to prevent damage.
"Motion Sensor" and "G Sensor" are the same thing, just showing that the chip can detect when it's being moved.
Correct, motion sensor and G sensor refer to the same device (accelerometer).
There is no difference apart from the name.
I have looked in every menu as far as I know, and I do not find the compass anywhere.
There are actually two "motion" sensors on the G1.
The first is the accelerometer, similar to the iPhone. It detects motion by changes in gravity on three axes. This does not mean the phone has to make big movements to detect anything. The force of gravity is, in part, determined by the distance between two objects, so the phone does not have to move for the sensor to get a reading.
The second is a digital compass, I think that there's a Nokia that has one but the iPhone does not. This, as the name implies, reads the earth's magnetic field and determines which way the phone is pointing.
I'm working on an app that will use both of these to allow the user to examine a virtual 3D object.
Actually I finally found it. It is not called 'compass mode' as advertised. You go into maps - then street view. It will say searching I think .. then you touch the spot it tells you to and there you are .. walking down the street. I don't know how often the pictures are refreshed, but must be fairly recent because I can see that I need to get my lawn mowed !!! of course .. it seems I always need to do that with all the rain here in florida, but I would rather play with my toys.

Why you are in that screen hit menu and compass mode is in the bottom lower right corner and will react to your movements.
Thanks ... fouund it!
Hi xda-developers!
I'm working on a application that measures the users heart rate, breathing and register movement.
I have already researched the field of existing sensors, and whats on it's way to release.
One of my biggest concerns is the use of an external sensor vs an integrated sensor in the smartphone - and thats why I need your expertise!
If I use an external sensor, what elements would help me store data about heart rate, breathing and movement? and is there a sensor you would recommend? am I better of using only the smartphone sensor?
One of the other things I have been thinking about is the datatransfer from sensor to smartphone.
I would like to get data day and night, with a sensor that is small and light-weight.
What transmission-type would you use? ANT+ or Bluetooth? or something different?
Oh, one last question:
How would you power a sensor like this?
Any help is appreciated and can't wait to hear your input and comments! :highfive:

In my opinion, I would like to say that the best option is a sensor with integrated bluetooth, because that will give a "generic" plus to the project (Every smartphone has bluetooth sensor) and i think that it will be easier to configure the conection (you mean datatransfer) between your project and the phone.
Regards and best of luck, it seems it's a good project
Hi everybody,
Can anyone tell me how to use the sensors(proximity, magnetic etc.) on Nexus 4??
I mean as we have accelerometer sensor installed on my N4, can I use this sensor to show the actual speed of my jogging?
my digital sensor has stopped working, I have already analyzed the smart doctor and does not recognize it. any tip to make him come back without being the exchange?
Which sensor ?
Hi everyone,
I would to know if this tablet has a gyroscope sensor. According to gsmarena, there is one, however according to an app called Gyroscope Test there is not. Also apps that required a gyroscope doesn't seem to work. I don't know if the kernel I installed simply doesn't support the gyroscope.
Thank you
Hey, I just downloaded aida64 and gyroscope test to test it.
Aida64 shows me:
LIS3DH Acceleration sensor: x / y / z
MS-3R(YAS532) Magnetic sensor: x / y / z
MS-x Orientation sensor: Azimuth / Pitch / Roll
AL3201 Light sensor
Screen orientation sensor
If I open the gyroscope test app it shows me:
Device Model ID: Samsung GT-N5110
Detected hardware
Gyroscope: No
Magnetometer: Yes
Accelerometer: Yes
Google Cardboard compatible: No
If I run the simulation in the app, I was able to looking around by moving my tab. It was smooth and correct.
