[TriEmbed] Proposed talk for September's meeting

[Grawburg]

Rodney,
I already have a dual-sensor, one-wire temperature monitoring project that I had students make last week at the science museum.
I also have an AirPi running with temp, humidity, pressure, and a couple of other things.
I'm aware that the Pi doesn't handle analog by itself; I had the impression Lee was going to talk about analog signals
with the Beaglebone Black.

The Raspberry Pi doesn't have any analog data channels, but all of the measurements listed above are available as I2C data sensors, so it will work well with any device that supports I2C (Raspberry Pi, Beagle Bone Black, even the Arduino, plus many more).

 
You should also look up the one wire weather station (uses the one wire interface - different than either SPI or I2C) and includes nice weather devices that can be controlled by any of the previously mentioned embedded boards.  I have a weather station I put together using a Raspberry Pi and OWW components.

I'd like to hear how the Beaglebone compares to the Raspberry Pi for this application - especially the analog data gathering.

Subject: [TriEmbed] Proposed talk for September's meeting

Lee Atkinson has been working on Beaglebone Black's using the Cloud-9 IDE and Node.JS to connect to "Fidget"s sensor and actuator breakout boards.

I thought it would make a great presentation talk for the Sept. 8 meeting. Lee's example is to gather data from voltage and current, temperature, humidity, barometric pressure and light level sensors and do data logging, and filtering for triggers to set or unset a relay(s). I think this dovetails well with this month's talk on sending that data to an online datastore for aggregation and analytics.
