bhadresh Posted October 9, 2012 Report Share Posted October 9, 2012 I'm trying to use my wireless doorbell to switch off my water pump. The problem is how to use the receiver signal to latch a relay. Search the net but no clear solution found !I've driven LED from a speaker wire with transistor (doorbell receiver circuit) but don't know how to use this signal to latch a relay. I'm planning to use 6v relay. I've try to drive relay with transistor but no success.Pl. have me some idea/schematics. Quote Link to comment Share on other sites More sharing options...
boblim Posted December 16, 2012 Report Share Posted December 16, 2012 It shouldn't be difficult. Maybe a photo of your wireless door bell will be good.You can also buy a wireless remote control, which will definitely solve your problem.
