   No, I'm looking at pressures in air handling systems.   
      
   In systems that I've designed previously, someone   
   else selected (very expensive!) transducers and   
   I just had to interface with them.   
      
   But, those were industrial systems with dedicated   
   staff to keep them running, calibrated, etc.  You   
   cared about the actual "numbers" from the sensors   
   because you were controlling "regulated" processes   
   and needed to document compliance/exceptions.   
      
   I'm trying to leverage some of those algorithms but in a   
   cheaper consumer market where stuff "just has to work".   
   I don't care about numbers as much as *trends*, using   
   adaptive algorithms to sort out what's "normal" from   
   "indicating".
