Hi everyone,

I would like to make a garden ornament that turns on when someone gets near to it. The sensor will power a small 7-8 volt DC motor. A PIR (i think thats what you call them) I have seen has 2 adjusters, one is for sensitivity and the other is for duration, this would be perfect except it says it will only put out 5 volts and thats not enough. I have searched for a PIR that can put out more voltage but cannot find anything.

Can someone advise me on what I will need to purchase and how I put together without trying to explain it with a schematic i.e. I need it to be explained in the simplest of terms as my knowledge of this stuff is virtually none existent.

If someone could advise me I would be most appreciative.

Thanks in advance!

 

Your 5 volt output can be used to turn a transistor switch off or on.
The Switch will control the voltage to your motor.

 

Thanks for your reply. I have just Googled "transistor switch" and it seems like there are loads of different ones, what type do I buy and where do I put it, does it plug into the PIR? Does it matter what type of PIR I buy? I have seen this one; https://thepihut.com/products/pir-m...nt=758602485&gclid=CMmjy82Hks4CFQcz0wod6okMaA

Would that work?

 

Actually I think it was this one I was originally looking at; https://www.proto-pic.co.uk/pir-motion-sensor.html?gclid=CMnZ5_eIks4CFc4V0wodrzwLDQ

 

Read some forums and looked on Youtube and all I see is a mass of wires and electronics. It appears as though it is a lot more complicated than I first thought. I thought I could just buy something to replace a simple on/off switch to turn the motor on when motion is detected. Would of been great for my project but I guess I'll just stick to an on/off switch, to complicated for me and looks a mess having all them wires.

So you can buy a plug in and go. Thanks block a spirale, actually I found one that can take lower input so it will run from my 7.2v Ni-mh rechargeable battery pack (I hope). http://www.ebay.co.uk/itm/371362170517?_trksid=p2060353.m2749.l2649&ssPageName=STRK:MEBIDX:IT
