It Works!
The chickens are staying out of the veggie patch now, every time they go in, the motion sensor trips and switches on the sprinkler.. they don't stay in there for long :)
I just have to remember to switch off the water before I go in there now
:rolleyes:
I'd like to thank...
The simulation fails.
I haven't breadboarded the circuit yet. That'll be next :)
Thank you all for your help. I'll breadboard it and let you know how it goes.
Thanks Colin,
Is this what you mean?
One other final question. As I understand it "ground" is just a point of reference from where all other voltages are measured.
In the lower circuit, if I remove ground from the circuit, the positive side of the dc current source is +8v and...
Thanks Colin55,
I've been playing around with livewire and trying out different things. to utilise components I already have lying around.
The bottom circuit seems to work to drive the solenoid. Why though is the 10k resistor needed on the signal line?
THe top circuit however...
repost of the image..
@KMoffett: sorry if I used an unsuitable site, but I don't understand the relevance of the "g-rated forum" comment. AFIK, I didn't swear or post anything that wasn't g-rated. Could you please expand on your comment?
Thanks for the quick responses,
I haven't done a circuit diagram as yet, just some exploratory surgery with the multimeter, on the motion sensor. However I can put something together with mspaint and post it up.
Using the 12v power supply would be easiest, I was concerned with the battery...
Hi,
I have a motion sensor door chime/alarm and would like to alter it slightly to drive a solenoid. The alarm is designed to run off a 9v battery, but the solenoid requires 12v.
Also the signal line from the sensor goes positive at 2.7v going into the IC that generates the chime sounds...
