I am trying to design a remote kill switch for a childs motorcycle that a parent could control from a remote location. I have a (i believe) a uhf car starter/ alarm with several functions. What I need this device to do is, when activated will close a remote circuit to ground, thus killing the motor, and open to allow for restart. The signals coming from the receiver are millivolts. MY question is I need some sort of relay that will operate under millivolts to open or close the desired circuit. I have a PRMA2A05 reed relay, but cannot get it to work until the voltage is >3.0 volts. Can I make this relay work or is there another alternative. My knowledge of electronics is very intermediate at best. Any suggestions would be appreciated.
Thanks
