I am a relative noob with respect to electronic circuit design, though not completely incapable (soldering skills and so on). I have a fairly simple project and need some help/advice.
I have a data gathering system that accepts user-provisioned sensors. The system can provide either 5v or 12v to the sensor and requires the output to be 0-5v. It can calibrate the output in the software.
I need to capture temperature, barometric pressure, and humidity. I'd like to have some degree of accuracy, but in trolling through sensor catalogs most are fine (e.g. +/- 1C for temp).
But that's really the point. I'm overwhelmed. There are SO many sensors, I can't figure out what I need. There are all kinds of them, and the ones I find that are "simple" all are digital (output a stream via USB for example).
Can someone here help? I need some advice on sensors that you've used that would work for me. Or pointers to projects with designs for this sort of thing. Or ... any help at all, really.
Thanks in advance,
Chris
