[Bldg-sim] Remote Sensing and Real Time Analysis

Hello:



Apparently, there are a lot of folks out there using Hobos in their classes. So, here is the spreadsheet and the instructions for its use. I've included the instructions as a .PDF and .DOC so you can edit for your use. If this doesn't make it through the list server, I'll post on an ftp site.

Arpan,



Plotting T/RH data from a Hobo onto the psych chart is the most interesting. I think you could do this with Climate Consultant if you had the time to reformat it to make it think it was a EPW file. Then you'd have a nifty plot along with all the things that Climate consultant does. I also had animated plots, moving carpet plots, etc., all of which were documented in some early 1990 papers (see my resume for the reference, available from our web site).



I'd be happy to share the spreadsheets I use in my 633 class if folks are interested. It plots Hobo data on a super simple psych chart for indoor and outdoor conditions, written by Dr. John Oh who wrote the SOLRPATH I use in my class as well.

Professor Haberl

For the list of items posted, would you recommend investing in any specific software, in addition to what may already come with the equipment?
Thank you for your valuable input.

Arpan,



I think you're wasting your money on the IR camera. One drop and its gone...also, although it takes fun photos, you money may be better spent buying portable T/RH data loggers, light meters, acoustics meters, air flow sensors, IR temperature sensors, etc. Then, you'll need specific experiments for them to use (LBNL has quite a bit on this for educators, as does the USDOE, NREL, ORNL). Les Norford and a few others also have some nice on-line experiments they use for students like his "Elf House".



I use about 1 doz Hobos in my classroom for them to take home and record their indoor T/RH for a week, then plot on the psych chart along with outdoor T/RH and comment, after using the Climate consultant software in class. This really gets the point across about psychrometrics.



Also, try getting your hands on an old Vital Signs kit. This contained a list of instruments, experiments, etc. You'll also need software to decompose the T/RH onto the psych chart, etc. I think the price tag was about $5 to $10k for all the instruments in the kit...a really neat toolbox.

Dear All --

A friend of mine unfamiliar with the joys and camaraderie of our user group, is planning the purchase of remote sensing and real time analysis equipment for college students. I would love to hear discussion about
a) whether this list is worthy of its value!, and
b) if the unit prices seem realistic, suggested makes and models

$ 500 - LCD Weather Station Variable Display Monitor
$1700 - Weather Station/Sensor Monitoring Computer
$ 350 - Field Kit: Set up, Mounting Panel, Cables, Batteries
$5995 - Infrared Camera
$ 450 - Hand Held CO2 Meters
$ 250 - CO2/Temp/RH Remote Sensors and Loggers
$ 200 - Wireless Rain Gauge
