How can i take the best sensor values ?

Projects General Guidance

Hi,
I'm developing a project to measure the comfort in a work place (classroom, office,...) I want to use differents sensors. But I have a problem, because I don't know which is the best way to measure. I was thinking of using a servo with 4 stations to take 4 different values for each sensor. But I think this idea isn't going to fit because it doesn't give me the whole stat of the place. Maybe using a portable device which i can move ? I don't know.

I think you'd need to know what sort of sensors they were, what environment you were in and what locations in that environment you wanted to taker readings from. Certainly the Arduino can make a servo move, but whether that achieves anything useful for you I have no idea.

Got it! First, I'm going to decide the sensors and then I'm going to define the device.
I aprecciate your time.

Thanks

First define comfort.
Temperature?
Humidity?
Air quality?
Cushions?
Proximity to toilets (AKA 'comfort stations')?
A combination of more than one of these?

To define the comfort I'am going to use my country's legislation about work places

I have no idea what your country's legislation considers comfortable, so I'll skip the actual numbers and proceed to mention that in most spaces temperature and humidity are fairly even.
A notable exception would be near the HVAC vents where both temperature and humidity might be well within the acceptable limits, but still be uncomfortable. I personally don't like sitting in a flow of air from the air conditioning unit. A temperature sensor alone will not be able to detect this issue.

Yes, actually I want to use a sensor of temperature and humidity, I found this two:

Between this two sensors is there any significance difference ?

No significant difference.
They both seem a bit pricey, though. For the same amount of cash, you can get 10 of them at ebay.

Thanks for your help and time, you are really helpfull.
I really aprecciate it.

this may be true, but if you buy one, you have full access to data sheets and a forum to ask.

I have a growing box of parts from e-bay that have no support, no wiring diagram and the supplier had the kindness to reduce the shipping weight by removing all that heavy ink on the chip.

I am hesitant to ask if anyone knows what chip it is. it has 14 pins and is black. it has a little dimple in one corner. (anyone ?)

also, my luck has been pretty good, about 80% of the stuff works. it would be a pain to order 10 parts, have no clue how to connect, then struggle with getting them wired correctly only to finally figure out it did not work in the first place.

once you get that good one to work, and you need 10 more.......
