| Mar 7, 2012 at 17:16 | comment | added | Martin Beckett | @Manishearth - I meant your home made radio was probably pickign up a wide band of RF noise from the magnetron - especially at close range. The light motion sensor is probably responding to electrical noise coupled onto the AC power line. Especially since its circuitry is built to be even cheaper than the microwave! | |
| Mar 7, 2012 at 17:06 | comment | added | Manishearth | Aah yes; a device that passes regulations shouldn't get confused by magnetron noise &c. Hopefully ;) | |
| Mar 7, 2012 at 16:55 | comment | added | Martin Beckett | @Manishearth - probably RF noise form the magnetron. You build consumer devices to 'only just' pass FCC/CE regualtions | |
| Mar 7, 2012 at 16:55 | comment | added | Manishearth | Now I don't know what the microwave did exactly, and I'm not sure if it would have happened when the wire wasn't hardwired but just held in the air, but it seems that a microwave can tamper with EM stuff as well. Motion sensors use IR. Then again, it could just be some microwaves(dont think that they can escape;but may be wrong) hijacking the long wire. | |

| Mar 7, 2012 at 16:51 | comment | added | Manishearth | Your explanation is probably correct as well, but this may be interesting: As a kid, I once built a radio transmitter. I didn't have a good antenna, so I experimented with a long wire. I once wired it directly to the receiving antenna of a commercial radio. I remember that the microwave caused static in the radio in this case. | |
