The IoT SIG project to monitor office environmental data. See the wiki page for setup details.

Two examples

• python - python-based gateway and mote code
• node - node.js-based gateway and mote code

• Improve the accuracy of the altitude reading by finding out the daily actual local atmospheric pressure at sea level and use that instead of using a hard-coded assumed value.
• Use Protocol Buffers (or similar header-based cross-platform message definition mechanism) to encode and decode the message over ZigBee more efficiently.
• Make the sound level average more samples over a longer period to get a more realistic reading of ambient sound.
