Re: Temperature and Humdity Sensor in a Smartphone

I disagree, I keep watching at my iPhone at the weather bar to see what the temperature in my city is but it would be som much better to read out real temperature like my car does...so I think temperature sensors is a great idea...only if you are interested in reading it you will make sure that the smart phone stays in teh similar environment during the measurement, that common sense practice applies to any sensor in any experiment...Kris

People with sensors have to continue to not rely on them completely and must check up on them and control them in order to get the most out of their devices.

That's a good point. Users of smartphones will become more savvy to all the sensors and know how to get a more accurate reading.

@DrQuine: "It also provides an interesting object lesson in atmospheric pressure in SI units."  Interesting! Thanks Dr. Quine. So what you're saying is the Bosch MEMS sensor can measure such small pressure changes that it can tell if you're on the 4th floor or the 30th floor and not be affected by general pressure changes in or outside building (weather, HVAC)?

Sounds like we need remote bluetooth temperature sensors for the iPhone - we care about the temperature outdoors as we drive, not in our pocket where the phone is resting. Maybe some of our car sensors can grant read-only access to our SmartPhones.

The sensor claims to be able to read your barometric pressure altitude within 3 feet (which would define the floor of a building). The challenge is that is needs to adjust for weather related pressure changes which could cause the readings to be off by 30 floors...

The same problem applies to aircraft altimeters - the pilot gets a "QNH" (I think) figure which is the sea level pressure at his location, puts it in and the altimeter is accurate.   So all you need is some way of (preferably automatically) telling the phone the QNH and it should be accurate...

Thanks. Yes I was disappointed when I found out an altimeter is really just a barometer with more math. (In other words, you subtract the local weather conditions.) Once I wanted a fancy watch with an altimeter on it for hiking but when I found out the altimeter was just a barometer, I decided it was just a toy (for my purposes). An altimeter wasn't going to keep me from getting lost.

Yikes. Sounds like altimeter designers are under a lot of pressure. (Bad pun I know.)

Hi prabhakar_deosthali: Yes it's like the smartphone is really a tricorder and communicator put into one. Even Star Trek didn't think of that one.
