hello guys i have one question
i want to stop ir transmitter its always on i disable air gesture and view without touch
but ir its always on
the infrared ir light we can see only when u record the phone
it is possible to disable this?? or to stop it ? plz anwser me
i cant post url because i have only 1 post i upload the picture in tinypic -> oi39.tinypic.com/35cidzr.jpg
That IR LED is also used for proximity detection I believe, which is something you cannot turn off.
Why do you want to turn it off so badly anyway? It will barely use power at all.
because i believe is not healthy for your head to receive continuity IR i am wrong?

If you start to fear your IR blaster, don't go out, stay at home. Because sun radiations are way much armful

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
Front camera, ALS, infrared sensor and what's the fourth one?
I found in the video that the led is on the left of the speaker and cannot be recognized as a hole,which is the same as S3.
I don't have any idea. I tried to search too, but I can't find any information. Anyone can help us?
I believe the fourthopening maybe a microphone for recording sound bits that can be added to the camera shot.
The four are (left to right):
gesture sensor, infrared emitter, infrared sensor (those two make up the proximity sensor, and then the camera.
Also even more to the left but usually not visible unless turned on, is the notification led.
I suggest you watch this:

IR emitter is on the top edge isn't it?

Yes, the emmitor for remote controlling is on the side of the top of the phone.

For a college project, I wanna control a bulb with android(call, msg, or bluetooth). Please help me do that..I googled a lot !
Thanx in advance..!

cheating way:
1. Buy a cheap cellphone, disassemble and use outputs from the vibration motor to trigger a circuit. There are plenty of transistor based toggle switches schematics out there. So when u call the other number it will light the bulb. Call again and it turns the bulb off. You also going to need to disengage the toggle switch for certain period of time before in can process and build voltage level shifter, stick to mosfets and DC.
2. Using arduino products, they have a very nice line up of hardware with interface extensions and great community/library support.
PS: If you never developed an app for android stay away. For a Semester Project you are better off buying 2xXBEE cards, slapping a mosfet to DIO pin on one XBEE module and connecting it to LED. On the second XBEE u can put a toggle switch and configure them to do the necessary actions.
Hello everyone, I recently got Note3.
Today, I looked at my phone through another phone camera and found a sensor which kept blinking all the time. (Please see attached clip)
To me, it seems like an infrared since human eyes could not see it.
Is this normal even I don't have air gesture ON?
Thank you

Very interesting. Mine too
That is the IR.
If you're using an IR remote app, and you press a key, that'll light up for human eyes to see.

How can it be the IR?
If you were using an IR remote app then you'd have to show the front face of the phone to the TV, which would make looking at the phone screen a bit of an issue.

You mistake my meaning. If you look at the top of the phone, you'll see a small dot next to the audiojack. That is the IR blaster. The blipping dot at the front is the indicator of the IR blaster. It lights up when the IR blaster is transmitting, to alert the user.
I was showing my phone screen to a friend on webcam today, when I noticed the IR blaster is supposedly active (see attached picture). But it would turn off when the screen would be off as well.
What gives? Is it supposed to be on all the time while the screen is on and wasting precious battery? If not, how do I go on about fixing this, or disabling the IR blaster altogether?
I'm sorry for the stupid questions, I just had to ask.
Thank you for reading!
That is not the IR blaster. The IR blaster is located on the top (top, not front) right side of the phone.
What you are seeing in the picture is the proximity/gesture sensors. They both use infrared and are both next to each other. So it's one of those.

You are absolutely right. I just tested this out on a camera and indeed, the top right corner lit up when I used a TV remote app. But like I said in the original post, forgive me for the stupid question. I just had to put my mind at ease haha
