Because there are devices out there using infrared to measure the temperature, so I'm wondering is there any 3rd party app to be used with the IR blaster to measure temperature.

I was playing around with my evo and used my nexus one to film some bootloader stuff and noticed that there was a purple led flashing wildly in the camera shot that I couldn't see with my bare eyes.
As it turns out the nexus one camera picks up on the ir from the proximity sensor, ego does the same. You can point your nexus cam at any ir remote at home to verify, its kinda weird. Any idea why they would do this?
here is some video proof, Video link : http://www.youtube.com/watch?v=nGqVDXAQ87A
Pretty much all digital camera sensors can do that. Try looking at it with your webcam. Digital cameras and SLRs and such may have an IR filter to get rid of that.

True story.
Its pretty much how the Wii works. There is no special camera in there. Those cctv security cameras can use IR for night vision; and I have used a camera and remote as a sort of night vision before.

I've also built a ghetto night-vision set using an an old camcorder viewfinder for the display, a cheap camera phone camera sensor for the camera, and a bunch of IR LEDs to provide "invisible" illumination. Worked pretty well :-D
Almost all camera sensors pick up IR ^^
Try with some phones or webcam, and you'll see =)
Edit : The only way to stop the IR, is to put a filter
After lil more than 1wk, I still discover a few new things about this amazing phone. Particularly the built in sensors. I read somewhere that S4 is the first smartphone with hygrometer to measure humidity. Cool.
But i have no idea that there's also the magnetometer is there also to measure magetic flux and field strength. I had fun moving it close to electronic equipments and an old phone case with magnetic clasp and see how the reading changes. testing near MRI is of course not rec.
Of course the barometer and thermometer are there too.
Between the two apps: weather signal and weather station, all these sensor readings can be accessed live... amazing.... forget about accessing s health to read sensor...
the only thing iphone got above s4 is the fingerprint reader. But i am quite certain that samsung won't let that by on their next iteration of the galaxy... Maybe they can figure out how to make a pulse reader and pulse oximeter sensor to build into the phone? I think built in body function sensors could be the next big things...
Btw, i am about to enclose my S4 into a watertight case. I imagine the barometer, thermometer and hygrometer will be a little less accurate .
How to read all the sensors data? But not the raw machine data, preferable with human readable interface?

I personally use Elixir 2 https://play.google.com/store/apps/details?id=com.bartat.android.elixir&hl=en

I don't think there's a thermometer on here

I showed the s4 sensor readings on weather station..... my friends thought I was just pulling the local weather numbers off the internet and said their iPhones could do that too... I don't think they completely believe me that the numbers on the s4 were not from internet....
How does the thermometer measure anything but the battery temperature? I figured that the battery temp would overshadow anything else it could measure. Maybe my phone just runs too hot?

I've just encased mine in a watertight lifeproof knockoff. So now these sensors are not as functional. I do see yr point about battery temp and i think weather station actually has a pro ver which try to compensate for even the presence of battery heat. I am fairly certain though that the sensor doesn't just measure your battery temp and can't measure anything else....
Is there an app that utilizes the built in barometer to display pressure trend over time? The barometer was a big reason I picked this watch.
Thanks
barometer
install watchmaker and you 'll could add barometer on your watchfaces as you want

It dawned on me the phone uses a IR light for iris scanning. If we could get root, maybe it could be used as an IR blaster in the future. I know, wishful thinking, but intriguing nontheless.
Does this have a Barometer pressure sensor?
Specs on gsmarena say so but when I open apps like accurate altimeter, it says there is bo sensor to measure pressure
I noticed the same.
seems like a mistake even on samsungs website. They also say there that it has a barometer sensor.
