Home automation

  1. 1. 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.
  2. 2. How it started Online real-time Geiger counter to monitor radioactivity in air Live near Garching Forschungsreaktor Assembled 2 weeks before Fukushima 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
  3. 3. Android phone cam as radiation detector Natural radiation: • background radiation • flights in airplanes • Potassium 40K KNO3 fertilizer, Pokelsaltz bananas
  4. 4. 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
  5. 5. 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.
  6. 6. Keep in touch with mom 2000 km away 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.
  7. 7. Mobile Webcam for places without internet and power • See if right time to go to skatepark , play football or ice hockey. • MobileWebcam.apk for Android, free, good support from developer. • 1 HD photo/10 min. 20 MB/day. GSM O2 data 15 EUR/month. Samsung 90 EUR. • Weather-proof box with LiPo 4V, 16 Ah. 2-3 months attendance free. Box 50 EUR. • Solar charging possible.
  8. 8. Temperature sensor for Pachube – Cosm www.sarmalink.com • Video and temperature monitoring from anywhere • Free Windows software, cloud storage • USB thermometer stick • Alarms by email • software motion detection • movie generation
  9. 9. Summary barbara320.gotdns.com 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
