LIGHTS OUT, a possible life saver. An acquaintance fell in the washroom and was unable to raise attention for thirty hours, and never fully recovered. The monthly cost ($50) of wearable alert bracelets and the habit of not wearing them is a large risk to seniors living alone. This alarm system, based on an ESP8266 and a php web app, alerts friends that a bathroom light has been left on for way too long. The link to the presentation docs is here.

Jim’s presentation focuses on interfacing sensors and devices ( modules) to microcontrollers followed by actual examples. Two or more examples will be discussed using I/O from pulse inputs, IR transmitters/receivers, accelerometers, load cells, Bluetooth SPP and motion controllers.

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.
What are two things that an Internet of Things (IoT) device
1. An avenue for communication.
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.

The Internet of things now can control things wirelessly. Control of things using inexpensive radio frequency switches (operating on 433 Mhz) and an ESP8266 micro controller.
