| Jan 10, 2015 at 16:54 | comment | added | user64096 | i am also facing this type of problem and have not get any proper solution about this problem because we will face the problem to detecting the sleeping person then there are more possibilities 1. does person sleep on the floor or on the bed... so over all what i understand we have to use many sensors in this project and alot of coding..... :) | |

Added periods at the end of sentences and removed a duplicate "to sleep".

| Jul 2, 2012 at 10:20 | comment | added | Axeman | I think that in the next experiment I'll try an rfid tag (in a form of bracelet, or ring, or something like) and a couple of medium distance RFID reader on each door, to detect not only the number of peoples entering or exiting a room, but also WHO they are (so the system can have a configuration for each person). And for the one-time guests... we'll cuff them to a tag when they enter the house... :D | |
| Jul 2, 2012 at 10:08 | comment | added | Axeman | In this very moment, I'm testing a setup with a camera for each room and infrared illuminators, to detect differences between "usual" room arrangement. it's very reliable with full light, but in the dark it fails because infrared alters colors. the microphone setup has one big problem: how do you discriminate between YOU snoring/talking/whatever, and the "little peoples" in a television doing the same? :-) | |
| Jul 2, 2012 at 9:16 | comment | added | Vorac | @Axeman, calibrating the sensitivity of the sensor is a good idea that I had not thought about. Have you tried those PIR presence sensor that Russell McMahon mentions? Further, what do you think of my idea of using microphones (they are absurdly cheap :D) to detect human speech, walking, snoring, breathing, etc? | |
| Jul 2, 2012 at 8:49 | comment | added | Axeman | I have the same problem, but we're two humans and 4 cats in our house. And PIR doesn't works reliably with pets. I tested many of them. they can be calibrated to filter out ONE of the cats, but when they enter in a room toghether, PIR triggers anyway... | |
| Jul 2, 2012 at 8:33 | comment | added | Vorac | Apparently, PIR is the way to go. Maybe I should toss a dozen of electret microphones and a contact switch at the main door. If you are interested, check this thread an year or two later - I hope I'll test all this and post a principal schematic of a working, extensible, robust, failsafe, chap (setup & maintenance costs). :) | |

example usage to narrow down the question
