http://community.pachube.com/node/296 has an Arduino version of what you are asking about... But there are lots of versions, this is just a quick DIY search.
A friend monitors buildings and does temperature, air velocity, etc, etc, data logging and sometimes takes actions (and even emails or calls or downloads data automatically), but he charge commercial prices for commercial units with custom programming. If you want to monitor many things, you will be spending a fair amount on sensors, or rolling your own. Also, figure out how you are going to deal with the data you get. How fast do you want to sample, do you want to do running averages or just keep all the data points, where are you going to store the data. Is it just for a short run or are you going to 7x24 data logging, or log data around an 'event'. ... Lots of options, lots of choices, lots of different solutions, and lots of different price points depending on your needs. ------------------------------------------------------------------------------ Learn how Oracle Real Application Clusters (RAC) One Node allows customers to consolidate database storage, standardize their database environment, and, should the need arise, upgrade to a full multi-node Oracle RAC database without downtime or disruption http://p.sf.net/sfu/oracle-sfdevnl _______________________________________________ Emc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/emc-users
