Hey,
Has anyone played bought these cheap wirless infrared sensor,they look
too good to be true at $15 + shipping via ebay
http://cgi.ebay.com.au/Wireless-Inf...yZ106188QQssPageNameZWDVWQQrdZ1QQcmdZViewItem
Do they work as claimed seller says 50m straight distance and they set
off a led or bell,maybe only reciver distance?
Question:
using a relay off the led or bell how could I easily set these to make a
continuous alarm,powering either a stobelight or siren.(I gather these
just send a signal when the intruder passes the beam)
Or how could I use resistance in the circut to set a continuos alarm
through a pre-existing alarm panel?
these are cheap compared to the dse models at $100
had to ask before doing home work!
TIA
