hello everyone,

what i have is a motion sensor, with a pcb inside. Basically the pcb has a mono jack attached, so when the sensor is triggered, instead of making a noise, a signal is sent along the phono cable, to a panel on the wall, that alerts the nurses in a care home. i have attached photos of the pcb, is it possible to copy this onto a breadboard? or will i need to get pcbs made up? also does anyone know what the components are on the pcb?

if anyone knows how to make this circuit on a bread board, or draw a diagram so i can make one then please get in touch! thanks

Looks fairly simple, it is just a bog standard 5v relay with a reverse biased diode across the coil, a transistor (NPN probably) and a what appears to be a resistor (can't make out the markings).
Where does the red wire go?

The relay is one of these here: http://datasheets.hypertriton.com/axicomrelays.pdf which is a single pole change over, non latching V23026A1001B201.
The 3 remote wires go to the common, NO and NC contacts of the relay.

As a side thought, would normal alarm PIR sensors do the same job? They may need a little bit of jiggery pokery to make them output a change over switch but shouldn't be that hard to achieve.

If I connect that to a power supply will it simply flash? and if not what's it for? Can I blow it if I get the polarity wrong? Thanks in advance.

Sounds very interesting and helpful! Thanks for sharing Grantos.
Yes You want to superimpose it in a new breadboard or new PCB. You can contact PCB manufacturer.
Thanks

Just I am recommending you to visit online where you get enough idea about pcb those will helpful for you.

Thanks!!!

"PCB is well and good, there are plenty of places more expensive than your service.I’m not recommending but perhaps
you could check out PCB forum about many resource.
Thanks!!!!!"
