Available Sensors

Is there a list of sensors that I'll be able to use with the WeMo Maker?

Well, my assumption is...  like the page says at:

http://www.belkin.com/us/wemo-maker/

 

That "Once connected, the WeMo Maker allows you to monitor a variety of 5v analog sensors."

 

I'd assume however after reading lots this is not actually "Analog" with an ADC that people assume.  

 

It appears to be an input that is triggered when you pull the sense pin to ground?

Re: Available Sensors

That sensor pack from adafruit looks like a good start. Thanks for the link!

Re: Available Sensors

I just ordered it, and since it in theory is coming from Manhattan it should be here really soon.  (hopefully UPS can handle a 3 hour drive in less than two days)

Re: Available Sensors

I might be missing something - the WemoMaker appears to only be triggered by an off/on sensor switch.  To me most of those look like analog measuring devices?

 

It would be good to know a bit more about the WemoMaker specs, like what is the input sensor's on/off voltage threshold?

 

And looking at the future, is the input sensor a threshold sensor only or is it an A/D input and we can expect to be able to read the input voltage as well?  Will the input levels be adjustable?

Possible Sensor options with online sources

[ Edited ]

To start here are examples of sensors that appear to be compatible with the WeMo Maker. IE 5V operating voltage. TTL

 

Motion sensors

 

Digi-key sells some PIR type motion sensors with pretty fast shipping. Here is a link to 5v Lead free RoHS type. You would have to solder leads on to them.

 

http://www.digikey.com/product-search/en?FV=fff4001e%2Cfff802b4%2C450000f&k=PIR&mnonly=0&newproducts...

 

Alternatively this sensor could work too although I've never ordered from them before. Since it doesn't mention anything about being lead free or RoHS I guess it's not.

 

PIR alternative site

 

Flow Sensor

 

Here is a more expensive example of a flow sensor that is 5 v with no external circuit required.

Light sensor

 

Here's a pretty easy to interface light sensor and very low cost and with a built in circuit. Also make sure you observe the wiring for the part you order. It might be a good idea to order multiple units in the event of incorrect wiring.

 

Part Number: OPL550

Datasheet: http://optekinc.com/datasheets/OPL550.PDF

Link to digikey: http://www.digikey.com/product-detail/en/OPL550/365-1115-ND/498718

 

Pin # Sensor 
1      Ground 
2      Output 
3      VCC  

 

Note: the pins 1 and 2 will have to be switched to accommodate the proper connections on the WeMo...

Other sensors

 

(Make sure you select 5v type before you order as this link isn't filtered by 5v)

 

http://www.digikey.com/product-search/en/sensors-transducers

 

 Before you start refer to this post for proper connection to the WeMo especially the power supply isolation aspect...

 

WeMo Maker Tech. Specs.

 

FYI - I do not work for Digi key and I'm not benefiting anyway from the links displayed. I've used Digi-key for hundreds of orders in the past they are very good shipping speed wise and for service. For example most of my orders were place before 4:30 pm EST and they arrived next day. Almost 95% of the time.

 

I'll post more in the future. But before you order do your research first!

Eric

Re: Available Sensors

This is GOLD!

 

Thanks for the link, I had a bunch of photodiodes laying around here somewhere, but I would be interested in monitoring a temperature sensor and @ a certain temp. trigger.

Great find! I'll pin this for other inventors to see. Kudos! Smiley Happy

Re: Possible Sensor options with online sources

I've updated my orginal post to include a light sensor and more information.
