Fr. Robert Ballecer, SJ While you were showing us the Cayenne interface, you said it also works with ESPies (?) but I didn't know what that was, so tried to look it up.

 

After reading some datasheets, I still can't tell if it's a WiFi adaptor for Arduino, or a standalone device. Can you explain what it does, and maybe show a quick project demonstrating its functions?

 

thanks

It maybe referring to sparkfun.com/products/13678

The ESP8266 WiFi module...

Black Merc There are a number of sources selling this or similar products, but that's not what I was asking. I know where to buy it, I just wanted a clearer explanation of what exactly it does, as I mentioned in the second paragraph of my message. Thanks.

I'm not sure anyone could write up an explanation that is better than the one on the SparkFun product page. If after reading it you have specific questions post them and someone can probably elaborate on SparkFun's description. Also check out the tutorial project example on the SparkFun page.

Paul Hutchinson Thanks, but that was one of the articles I read yesterday when I was trying to understand exactly what it does. I know it can work as a wifi adapter for Arduino, but you may notice from the question that I posted, I'm trying to understand if it has any standalone functions. Can it interface with sensors directly, or does it need to be connected to a microprocessor? The Sparkfun article (the text of which also appears on other sites attempting to explain the functionality) mentions "allows it to be integrated with the sensors and other application specific devices through its GPIOs ", so that led me to inquire whether it needs to be connected to a microprocessor like Arduino, or can it interface directly with sensors.
