This is about an IR controlled door opener.
The idea is that an IR signal activates a relay which in its turn set the voltage over the electronic lock to 0 -> door is open. I.e in idle mode, there is 12VAC over the electronic lock. -> door is locked
My problem is that he relay is fluttering. There are two cases:
1) In idle mode. I.e there are no IR signal
If I take away the voltage over the electronic lock, the relay stops fluttering and IR + relay works as intended.
2) If I activate a fluorescent lamp close by. During the lightening phase of the f-lamp, the relay flutters.
The IR sensor and the relay circuits are driven by a 4.5 v battery, so there should be no interference over the AC net.
Also tried to drive the electronic lock with 12VDC - same behavior
Any advice on this issue, would be highly appreciated.
Thanks,
