They are to be installed at localized or remote sites for //in situ// meteorological data collection. As of late, the proposed data to be collected is that for temperature,​ humidity, and atmospheric pressure. The station will be able to record data at various intervals, though intervals less than 15 minutes would probably not be practical.
  
 +The stations are to be powered by solely a small solar panel and a supercapacitor. With these components and a properly configured MSP430, indefinite runtime could easily be achieved. The only limiting factor is how much data can be stored. ​
  
-===== Data Extraction Units =====+==== Sensors ​==== 
 +The data we would like to sense with this system is temperature,​ humidity, and pressure. Due to high cost, pressure sensors will likely be bought after the initial stages of the system are designed and completed.
  
 +Temperature:​
 +Dallas DS182x. The DS18S20 ({{::​ds18s20.pdf|datasheet}}) is a very small, inexpensive,​ and precise (+-/0.5C) one wire thermometer. There'​s also already a library for using it with the MSP430. There are a bunch of other temperature sensors out there, so this is by no means the only one we can use. The MSP430 itself has a built in thermometer,​ but I do not know how reliable or precise it is.

 +Humidity:
 +It's a bit harder to find a good looking (and well documented) humidity sensor. These are two I've been looking at:
 +  *{{http://​www.sparkfun.com/​products/​10167|http://​www.sparkfun.com/​products/​10167}} or 
 +  *{{http://​www.sparkfun.com/​products/​10239|http://​www.sparkfun.com/​products/​10239}}
 +
 +They'​re both $10, but have a few fundamental differences.
