best hardware for monitoring on/off states
Posted: Sun Sep 09, 2007 7:42 pm
I want to monitor a number of doors and windows to see if they are open or closed, also, in a few places I want to check if an appliance is on or off. I think the best sensor for the doors and windows is a magnetic alarmtrigger?
What's the best way to get this info into a computer? The optimal solution would be easy to expand with new sensors for other readings.
I'm interested in both tips for the sensor network and the interface to the computer
I will have a separate 1-wire network for reading temeratures, wind and other weatherdata but form what I have read 1-wire is not optimal for on/off-sensors.
