Why are you doing this the hard way

I am powering a 12v AC landscape lighting circuit.

If so just use a Motion Sensor that's made for lighting most name brand outdoor low voltage lighting has one for there equipment.

That one is good for 50 watts

Definitely the right idea. Unfortunately it only stays on for 15 seconds with no adjustment possible.

 

hi Dock,
If you cannot find a suitable 12Vac version, this works with a12Vdc PIR module as per the eBay link.

Thanks. I like the relay idea but it is likely to be above my abilities.

 

With something like this, you'd just put a 12V relay and where the lightbulb is in the wiring diagram, then hook the 12VAC supply to the to the relay's NO (Normally Open) contact so that when it operates the lights go on.

 

Finally, I found one that is pricey but likely to work. https://www.ebay.com/itm/3139590370...F852GLa6vRiMymKD4wDXBlDPy62H|tkp:BFBMksPS0Ydg

Another ebay seller has one for half the price.

Slowly, the relay idea is starting to sink in. Would this 12V relay be appropriate? https://www.amazon.com/TWTADE-Elect...ords=DC+12V+Relay&qid=1650306468&sr=8-17&th=1

Please share the URL. I couldn't find it.

Yes, that would be very good.

Its STL110 not sure what the difference is.
Ebay 165420900286?

 

Yes, that would be very good.

To make I understand the wiring sequence, I start with 12v AC, use a rectifier to convert to 12v DC, then connect to the PIR you suggest and then that output to a relay and to the NO side, connect to the landscape lighting?

The Ebay 165420900286 you shared is for 120v. The one is shared is for 12v AC or DC.

Yes, mostly In the wiring diagram for the PIR sensor they show light bulb, that's where the relay coil goes.

A rectifier won't be enough you will also need to filter the output. Though they call this thing a "rectifier" it has filtering too. Without that you will have odd behavior from the PIR sensor.

I am drawing up a schematic with the rectifier in it to get your feedback.

Here is a rudimentary diagram. What do you think?

Almost. The wire coming from the PIR to the relay needs to go to the COMMON (pin 5) and then to the lights is 3 (NO).

Thanks Yaakov for the review. I made the adjustments. I have the 12VAC line coming into the relay on the pin 2. The amazon notes say pins 1 & 5 go together. Is pin 2 correct? Just double checking.

Forgot to attach the updated diagram.

No, here's the relay marked up. Pins 5 and 3 are for the 12VAC. When the coil is energized the switch moves in the direction of the dashed arrow closing the NO contacts.

The PIR sensor output needs to go to 7 and 8, the coil. When the PIR sensor is triggered it will power the coil and pul the contacts down closing the circuit to power the lights.

I think I made the adjustments. Diagram attached. I appreciate your patience.

Here is the adjustment but I am confused. You mention that the PIR wires go to pins 7 and 8. Those energize the coil. I thought a 12vac positive wire would go to pin 5 the common. I added a wire from pin 3 to 5 per your suggestion. Which pin do I connect to the 12vac lighting circuit. I thought that was pin 3 (NO).

I'm sorry. We are just not communicarting. The dashed line was explanatory, not a connection.

Let me draw out the whole thing for you. (Please excuse the rush job)
