Hi Everyone,
My dog keeps digging in my kitchen trash, so I decided to build a motion sensing alarm that I could place in the trash can!
So . . . I bought a "6 volt PIR sensor module" ( 276-033 ) from Radio Shack and a 6v Piezo buzzer and I hooked it all up with a six volt power supply. It worked but you can barely hear the buzzer. I'm guessing it's because the circuit board of the sensor module drops the voltage.
So then I bought a 4-5V reed relay and with that in there, it doesn't work at all because the module doesnt put out enough to trigger the relay. If I jumper the relay's signal terminal, the siren is plenty loud. So my question is, what the easiest way to increase the output voltage of the motion sensor? (I can't find a 1 volt relay! )
Any suggestions for a newbie?
By the way, in my frustration, hooked up a pressure sensitive switch to the buzzer and the dog no longer digs in the trash!!!
