Robust Indoor Display

I’ve been thinking about this for a while and have finally come to a conclusion that might be worth while. Consider if you will a home weather station with a completely customizable display reading data from the outdoor unit in real time.

An R. M. Young 26700 Meteorological Translator is all that’s needed. Personally I enjoy the retro look and feel of this type of display. It’s completely programmable via the onboard keyboard negating the need for the use of a computer. (Not that you would be able to find the configuration software online to begin with anyway.) While this device can operate as a stand alone display/data logger for individual sensors, it can also read serial RS-232 data.

Given the display can read serial data no problem, we can read data output from the automated weather station data logger. What’s nice about having the logger output data is we can pick and choose what it sends to the remote display to eliminate program complexity and unnecessary values being sent.

While operationally the AWS would probably record at 1 second, 1 minute, 1 hour, and daily intervals, we could also set a subroutine to output serial data once every 5 minutes or whatever deemed practical to be read by the display. The beauty of this is that regardless of what wireless connectivity is doing (uploading to WU, CWOP, etc.), it’s completely irrelevant as we have a hardwired data stream from weather station to user.

I’m unaware of any documented applications of someone doing this but I can’t imagine I am the first. I will update this post with more information when I am able to verify my hypothesis that this will work and make it a more finalized publication. Stay tuned…
