BUILD THE ALARM AUTODIALER

摘要

Anyone who owns a house and is away at work or on a vacation will at some point wonder "What's going on at home?" Not necessarily with the kids, but with the house itself. Even newer homes can have problems with heating, cooling, plumbing, or electrical systems which are easier and less expensive to fix when discovered sooner rather than later.This device will detect and report several common failures with household systems, so you can deal with them while they are still easy to fix. It's inexpensive ($60 or less, depending on your parts collection), easy to build, and doesn't require any contracts with monitoring services.
