Hello all.
I recently purchased a pir motion sensor (http://www.sparkfun.com/commerce/produc ... ts_id=8630), a rf link transmitter (http://www.sparkfun.com/commerce/produc ... ts_id=8946) and a rf link receiver (http://www.sparkfun.com/commerce/produc ... ts_id=8950). I'd like to connect the pir to the rf transmitter and send signals to the receiver which will be connected to an arduino 2009 board. As far as I understand (I'm new to arduino and electronics) I need a relay switch between the pir and the transmitter. The problem is that I do not know what type of relay to buy. Can someone help me , please ?
Thanks.
