Guess billybutternut doesn't know the startup current of the fan motor.

I'm still focused on whether the fan motor can be started from this PIR. If we're not going to know that piece of information then - well - this is a waste of time.

NO way directly, will require a relay circuit.

 

Thought about this as well. Also thought about one of those lamp screw base plug adapters. Decided against that approach because of two reasons: First, the TS wants this to operate 24/7, day/night. But there's a simple workaround on that - covering the photo sensor. Second, because this is to control a fan motor, the likes of which inflates those Jiggly Man's. Y'know, the ones you see on sidewalks drawing attention to an establishment. It could easily blow the circuitry when the motor repeatedly starts up. Even if it has a relay, it's not likely going to like all that current being drawn through it. The points may burn out or weld. So the simple approach - worth considering - will require further accouterments. I.e. a heavier switching circuit.

Also, we don't know if that screw in plug adapter would work. The fan motor may have 3 wire plug whereas the screw in plug adapter only has two. So we're beginning to rebuild Frankenstein. Simple? Yes. Practical? Eh! Within the TS budget? We don't know. Startup current of the motor - again, we don't know.

The skill set needed to wire one of those motion sensor security light heads to an outlet is quite minimal. Typically, being able to correctly use a "wire nut" and being able to tell the difference between black, red, and white wire colors. AND to read well enough to follow written directions.
AND, worst case, have the motion sensor 120 VAC output operate a relay rated for a higher current. That is a simple and easy solution. AND the security light systems include a timer to keep the lights on for a while.

AND, covering the daylight sensor.

I've been told I need a impulse latching relay. Just looking for a specific relay to use.

 

OK, Great. But we need to know the startup current of the motor.

For example:
Motor current 2.1A (running)
Motor current 10A (startup)

If your sensor can handle 3 amps and your motor is going to draw 10 amps every time it starts up - your PIR is going to RIP.

 

Relay required?
However requires a 12 volt pulse to activate.
I don't think they make a 3 volt version but the signal out from the PIR can be amplified.

 

Evidently no thought is given to utilizing a ready made, weatherproof, mains powered, security lighting motion sensor package, which includes the timer to maintain the output on for a selected amount of time after it is triggered.
My system is sensitive enough that it triggers on small animals running across the yard 30 feet away. And I can not imagine why anybody would consider using an adapter to screw into a light socket when rewiring would be so very simple..

What sensor are you using?

I never knew it was so easy. 8/

 

The simpler approach will certainly be an AC mains powered PIR security light system intended to power two 100 watt floodlights.

Thought about this as well.

This was my first thought. But @MisterBill2 beat me to the comment.

However, I rejected the idea because of a lack of knowledge regarding how many amps the Jiggly Man Fan Motor would draw. To this date we still haven't heard anything more than 2.1 amps. I assume that's RUNNING amperage and not STARTUP amperage.

I next thought of this, and comments have been made to this effect. But now it's getting more and more complicated. While, yes, it's a simple idea, the PIR and needed peripherals can run the cost up. Budget was another question posed to the TS which hasn't been answered. A cheap exterior PIR Motion Detector may be around $30 (US dollars). Add in the cost of a 120VAC relay, likely a small one with contacts capable of handling a minimum of 10 amps shouldn't cost much. MAYBE $10 (US) which I haven't bothered to track down the cost of. But this is what it would look like:

The relay contacts are connected to the line voltage; which are tied in behind the PIR. Neutral is tied in behind the PIR. IF the JM has a ground (likely it does) that too can be tied in behind the PIR. Simple. Less simple, but still simple. But bulky. At least that's my opinion.

The goal is to chase away deer day and night. Low voltage to control the 120VAC would likely be a lot cheaper as well as a low voltage relay, all mounted inside a project box sealed against the weather. And a small PIR without the flood lights (or other lights) WILL be cheaper.

But as I said, I don't care to follow this thread any further. Still, people keep quoting me and I keep getting alerts. I just HAVE to see what's being said.

That being said - I'm done saying!

 

The actual PIR portion is a three terminal device , Line in (black), Neutral(white), and switched line out(red). The cheap ones at Home Depot were $17 last time I checked. At a garage sale one with broken off floodlights stuck in the light sockets was $3. At Grainger they were quite a bit more, for ones with metal enclosures. There is a wide price range because of the fancy light fixtures on some of them. I don't recall the price of replacement PIR portions that were in one store quite a while back.
