I have made 3 alarm units wit arduino Uno and Pir sensor.
I would like to activate this alarm with a remote switch using IR.
Button A = alarm Activated
Button B = Alarm Deactivated
- What are the most used transmitters / button box
- Will they all send the same signal? So if i press one button al 3 devices will arm or disarm?
- If question 2 is true, then what is the best way to let each transmitter control just 1 Alarmbox.
I hope all is clear and you can give me a direction to go to.
These are used by a lot of people.
TSOP4836 are a good receiver.
In the US, we call them "key fobs" or just "fob". I don't know the source of that name.
With IR devices, the answer will be yes, since they are never used as part of a security system, like a car unlock device.
The Arduino cannot know which is which, unless you use IR remotes that are used for security and I have never heard of such a device.
The forum seems to be dying as I reply!
