Discover the advantages of Power of Ethernet (PoE)! PoE is a technology that allows one to only run one cable to a distant device, just an ethernet cable. The distant device not only receives network connectivity, but also power from the single cable. This is good for small low power devices such as ESP8266 (embedded controller) boards.  Hosted by Mark G.  RSVP on Meetup here.

Here is a link to the presentation pdf.

What are two things that an Internet of Things (IoT) device
must have?

1. An avenue for communication.
2. Power.

There are a number of ways to satisfy both of these requirements
simultaneously.  Item one can be fulfilled with:

– Wireless ethernet;
– Wired ethernet;
– Another radio based data exchange (nRF24L01 transceivers, Bluetooth)
to a network attached controller;
– 2G/3G (and friends) cellular connections;

I’m sure there are others.

Power can be handled variously by:

– A device specific transformer using a wall plug;
– A battery or set of batteries;
– A solar power panel w/battery;
– A power over ethernet cable;

I’ll discuss the ins, outs, pros and cons of these needs
and their combinations.

A presentation on creating a house monitoring device, with sensors, reporting via cell phone text interface. Pretty cool stuff.
