hi,
wanted give heads diy project called pi homeguard, flexible low cost solution custom alerting , data capture pi or other external clouds. idea first featured on pi blog , has been mentioned on magpi
project has sensor solutions for:
power usage, temperature, pir motion detection, door open/close, toilet flush, flood, ext temperature & humidity, rain gauge , wind speed.
wireless sensors self build because complexity handled in transmitter board firmware need several components minor soldering complete. each of sensors has had own challenges, example door sensor. ensure detection, open door event has held on several transmit cycles. on first version used 555 timer delay circuit hold signal on @ least 30 seconds. added cost, complexity , 555 circuit not easy build. handled in firmware , need 2 components, sensor transmitter board , magnetic door switch !
project on indiegogo first 100 basic working system power & temperature sensor £20 (excl shipping). 9 additional sensors can added needed.
let me know if need more details.
thanks,
jamie
can see live demo here or view same data presented via emoncms dashboard here.
