Hello I`m looking to build my own type of motorhome alarm .
The plan is to use about 16 car reversing sensor fix it the side skirts of the motorhome .
so this will detect people who approach the motorhome at night when im tuck up sleeping inside.
I will use the buzzer type without a lcd display
The buzzer will detect someone at a distance of 1.4m Then it will send a pulse signal to buzzer.what i want to do is wire the buzzer into a relay that will make the main headlights flash.at this stage.
Then as someone get closer say at 400mm the buzzer will make a constant signal which i want then a voice warning siren to come in again i assume via a relay.
The alarm will switch on/off by a remote control key fob
These system are available but cost about £700 so i thought i would give it a go myself.as they use the same equipment
The question i have is what type of relay do i need to be able to pick up the pulsing signal and make the headlights flash? is it simply a flashing relay?
Also what type of relay for the constant signal for the siren to come on
I think there is a one relay that detects the two signals ?
Thankyou for any replies
