MariusG Posted May 11, 2010 Report Share Posted May 11, 2010 (edited) Hi Everyone, If you are thinking about placing a small tag in the attic, basement, garden, green house, etc. and measure temperature, humidity, air pressure, CO2, etc., and post the measurement on a web page or inside a widget instrument posted on a webpage, blog, or profile on a social media site, then I have a nice solution for you. http://www.pachube.com/feeds/7277 A LabVIEW Cloud Instrument is an extension of the LabVIEW PC-based instrument into the Internet space. Sensors connected to WiFi tags send data to off-the-shelf Access Points which are part of the WiFi infrastructure that exists in enterprises, retail outlets, factories, and warehouses. Access Points route the data to a LabVIEW application running on a Server IP machine that reads data from tags and feeds the data via TCP/IP Write.vi to the Internet where specialized web applications like pachube receive the information for processing and display. Ian Bell posted an application note on NI Community, dated Aug 5, 2009 – Home Energy Monitor and pachube – which implements a very similar application. http://decibel.ni.co...t/docs/DOC-5425 Pachube, (http://www.pachube.com) as a “real-time data brokerage platform”, enables people to tag and share real time sensor data from objects, devices and spaces around the world. LabVIEW packages sensor data into a script pachube understands. Scripting can also be done in the tag as shown at http://demo.tag4m.com or in the Access Point. A solar cell powered cloud instrument is a cloud instrument powered by a solar cell. Application: solar cell powered Tag4M WiFi Tag connected to sensors sends data to LabVIEW VI running on local computer that feeds the data to pachube for public posting at http://www.pachube.com/feeds/7277 Application note attached. (or at http://test.tag4m.com/home/solarpowered_tag_final-2/) Application uses: 1) Tag4M WiFi tag ($140 single unit, comes with CR123A battery) purchase on the web at www.tag4m.com (Note: the Tag4M tag has a LV2009 driver for this type of applications.) 2) Sensors connected to tag: Temperature (DK part# TC1046VNBTRCT-ND $0.7 single unit -40;+125Deg.C +/-0.5Deg.C typical Accuracy at 25Deg.C), Pressure (DK Part# MP3H6115A6U-ND $9.66 single unit, 2.2 to 16.7PSI), Humidity (HIH-5030, DK part# 480-3294-1-ND $11.01 single unit) 3) LabVIEW VI – download from www.tag4m.com 4) Pachube - getting started with Pachube at http://community.pac....com/quickstart For solar cell inquiry please contact me separately at info@tag4m.com Best, -marius Edited May 11, 2010 by MariusG Quote Link to comment
