Home automation and sensors Quantify Self meetup, Combinat56, Munich 2012.05.10 by Janis Alnis
• Home automation becomes popular thanks to Internet.• Below my mentors house in Zurich.• Webcam, control of lights , window jalousie via iPhone.• Professional systems KNX and X10 are expensive.

Fukushima 11 March
• Geiger tube clicks are counted by Arduino microcontroller• USB connection with Linux PC webserver that makes graphs• No effect of Fukushima. Increased radiation during rain observed. That is normal effect.• Wrote a description at Instructables.com
How it started
Online real-time Geiger counter to monitor radioactivity in air
Live near Garching ForschungsreaktorAssembled 2 weeks before Fukushima

Android phone cam as radiation detector
Natural radiation:
• background radiation
• flights in airplanes
• Potassium 40K KNO3 fertilizer, Pokelsaltzbananas

Low cost, low power consumption Linux boards
• Every board has some compatibility problems.• Mini notebooks are best in compatibility. Ubuntu 10.10. • Mobile phones best in power consumption and functionality. Android programming not easy.
Alix-PC NanosG20 Foxboard Beagleboard
Bifferboard Raspberry Pi Samsung i5500

WLAN router webserver for automation
• Pocket router TP-LINK WR703N. • 400 MHz CPU. 1 W power consumption.• OpenWRT linux. Still works as router.
• USB hub, flash memory stick, HDD, NAS, FTP• HD Webcam + 1 W power, Logitech C270• USB sound card: Internet radio, mp3 player• USB GSM modem
• Webserver: weather forecast, revolvermaps, Pachube graphs
• Arduino home automation via USB: temperature, light, PIR alarm, sound level, switches Internet controlled power outlets wireless temperature sensors 433 MHz.
Selling on Ebay – kind of World conquering. AU, IT, CL, SG, PT, LV . Offering cloud storage. Car number plate detection Singapure.

Elderly people – no computer skills. Simpler solution needed.
• Router + Webcam
• WiFi client, internet from neighbours
• SIP phone, Skype phone, smartphone
•Arduino temperature, PIR motion det.

Summary
Tried different low power Linux boards for home automation . Wrote descriptions at Instructables.com.
Private ambitions fullfilled:• Can talk to mom and see how she is via a router.• Autonomous GSM webcam works:
Uses: summer house, construction site, graffiti prevention, bird nest, sport meetups, events, old people remote care, cemeteries, lakes, parking lots, skiing hill, plant growth, time lapse video.
Commercialization of ideas -not my strong side.
May be write or join some EU project?• EU Future and Emerging Technologies (FET)
to improve peoples lives
• EU objective: Health • Aging Europe• Improve life quality of older people
