Re: Available Sensors

Thanks for the info so far.

 

Can you please give a pin out of the + - and S pins on the Wemo sensor input?

For example, what does each one of the 3 pins connect to internally on the Wemo?

What voltage levels are compatible?

 

This would be very helpful.

 

Thanks!

 

Joe.

Re: Available Sensors

So, Jason, are you saying that the "S" terminal is the logic input that is internally pulled to +5V 

and the + terminal is +5V power and the - terminal is power and logic ground reference?

 

Just want to clarify. 

 

Thanks, 

Joe.

Re: Available Sensors

Jpack the link you provided is broken. 404. however when I looked at the datasheet for the PIR it's not setup to interface directly to the WeMo Maker how I think you have it set up. Off their website it states...

 

 

"...when the PIR detects motion, the output pin will go "high" to 3.3V and light up the LED!"

 

On the WeMo it needs to go low to trigger it. On top of that you have to make sure you have the jumper pin setup for re-triggering. A PIR sensor with a normally open contact that closes (shorts) when motion is detected is what you need. Did you get a chance to check out my mini tutorial? Try this to get a better idea of how it works...

Re: Available Sensors

Could Belkin maybe provide a list of known working sensors? The Inventors who have successfully used sensors too?

That's an interesting request considering all the possibilities out there.

Re: Available Sensors

Indeed on the low needed to trigger.  Most, if not all, of the usual arduino sensors are high trigger.  I'm trying to avoid using an arduino to change the triggering.

Re: Available Sensors

Thanks Canadadry, yes I did try out your tutorial. I guess I didn't realize the sensor I bought would go to high and not low. I'll have to keep trying to find a sensor to work with the Maker.

 

Sorry about the 404-error.

Here is the link: https://learn.adafruit.com/pir-passive-infrared-proximity-motion-sensor

Corrected... the forum added some extra characters to the link.

 

I'll keep trying to find other sensors. If anyone has some known sensors that they know work for sure, please post links and maybe give a tip on how you wired it to help some others out.

Re: Available Sensors

I've mostly used 24V sensors and know you can find them for almost any kind of electrical application. Can a 24V sensor sink to the WeMo Maker safely?
