Dennis DeLorme, on monitoring current and voltage in his river project.

Sleigh rides!  We will go for a [https://www.rochesterwinterfest.com/events/sleighrides sleigh ride at WinterFest] for our "January" social.  This is an annual favorite with the smaller geekazoids.  In fact I think we've even made the advertising photo for this public event, I suspect that mini-Schmidt is in pink on the top of the snowpile and my own blaze orange snowpants can be seen behind the horses to the right of mini-Schmidt.


Saturday, February 2nd, at 10 am.  
As some of you know I have working with my brother on his river water quality monitor project. He is the director of the Prairie Waters Education and Research Center near Valley City North Dakota (http://www.vcsu.edu/prairiewaters/). One of their programs is River Watch (http://www.vcsu.edu/prairiewaters/river-watch) where high school students monitor a river in their area.


Park along the road on Salem Road, the sleigh rides are north of the road behind the History Center.  
The monitor system is a solar powered data logger recording timestamp, temperature, pH, dissolved oxygen and conductivity.


Plan to gather around the Schmidt family. Sorry, no easily identifiable blaze orange to gather around this year.
Last fall I sent out a message asking what parts of the project people were interested in. I got 2 responses one asking how we picked components and one asking about solar power.


To cover these, the presentation will describe the history and evolution of the project over the last couple of years. It will be at a high to medium level. (I already covered specifics of the Bluetooth and WiFi interfaces in previous talks.)


I will also go through some of the problems and data that was collected last fall. Finally I'll demo the current WiFi interface using the actual hardware.

Dennis DeLorme on his Garagenator (that's garage doing the work of a refrigerator), involving WiFi/Web based temperature sensor/logger:

Did you have the family gathering at your place for Thanksgiving? Did you run out of space in the refrigerator? Did you wonder if the garage temperature was safe for overflow food storage? If so you needed the GARAGERATOR - the WiFi/Web solution to garage temperature monitoring.


In this presentation I'll describe how to use an under $10 WiFi module as a web server to monitor and log temperature. The "user interface" is via a web browser on a laptop, tablet, or cell phone. No special hardware or software is needed on the user side.


I will demonstrate the web server as an Access Point (a stand alone

network) to collect and download data. This requires no additional networking, so it is not dependent on a local network.


It can also be connected as a station on a local network and accessible to any device on the local network. I will describe how to do this (it is only a few lines of code difference). I don't know that I will be able to demonstrate this on the RCTC network - as I recall they had some additional interactions to sign on to their open network.
Also, annual KLUG officer elections, and PCIG officer nominations.


I will cover the hardware and software used in the project. For those that want to get a head start - the hardware is an ESP8266 module, a
DS3231 rtc, and a DS18B20 temperature sensor. The software is developed using the Arduino IDE with extensions for the ESP8266 (https://github.com/esp8266/Arduino).


NOTE: This is not an "Internet Of Things" (IOT) presentation. It could be connected directly to the Internet, but I lack the security knowledge (or, alternately, the level of stupidity) required to do that. It can, of course, access the internet via a local network - like other devices on a local network.
