Schedule a door opening system with battery
published: 28/11/15, 16:27
Hello
I need to automate the opening of a small door with an autonomous system with battery (s) and without going through the current 220 Volts.
A small programmer on 9 volts batteries should do the trick to operate a system to unlock an opening (latch system, hook, latch, ...), but I can not find anything.
I specify that the opening of the door once unlocked will be mechanical spring or its own weight.
I searched the net but I can not find a reliable solution at an affordable price.
There are indeed irrigation programmers that are generally simple and practical for programming, but the prices are high, and can we operate an opening system with this type of programmer?
For example, I use this very simple model and I measured that it was sending an electrical pulse of 1 volt for a split second. (which surely activates an electromagnet that opens or closes the membrane for water).
The operation of this type of equipment corresponds to what I seek but how to exploit the short pulse to trigger a mechanical opening without going through a complex and expensive electronic assembly?
I also saw that there were electric strikes (12 V 500 mA) that could work but I do not know if they operate in direct current and if it can be used with batteries,
or plugs like this but that only works on 220 AC:
Can you help me in my research for both the stand-alone battery programmer (9 volts),
and the opening system from the programmer?
Thank you for your bright and economical ideas!
