Fail safe way to remotely open a chicken coup

Like rjenkinsgb said, not at all - it's just an RS485 wired connection to a wireless transceiver.

Not for chicken.
Firstly, it was a detonator.
Secondly, it was an alarm.
And thirdly, it's a chicken.
Let it be an alarm.
Ultimately, however, incorrectly triggering an alarm is more damaging than triggering a detonator.
Let's just say an application must include both an alarm and a detonator.
After the alarm is triggered, at the remote control I have to decide what to do next.
One of the actions, peaceful, is the triggering detonation of a flashbang.
This is all to protect my dacha.
I will do this on my own territory.

i'm not sure but i think booby traps are illegal almost everywhere... don't look for help here... maybe the Mod should lock this thread...

maybe a better solution to your problem with criminals would be to use the tools available under your country's laws:https://en.wikipedia.org/wiki/Gun_control_in_Russia

I have found a remedy against criminals. I will use a 400 volt 100 thousand microfarad capacitor, no explosives. It will be discharged onto a tin wire, which will cause a strong explosion and possible contusion and a powerful sugar vaporizer based on a lithium battery to generate a large amount of smoke, the deterrent effect is guaranteed 100%

Sorry.
This is legal?

the only thing that might be legal (and i'm talking about where i live... the law might be very different where you live) is a "trip alarm" of some kind... here in the USA, there are devices which can be bought for such a purpose, but they can ONLY make noise, any more than that and they are illegal and unsafe... without knowing the laws where you live... i really can't elaborate more than that... however, think about using an obnoxious sounding loud siren that can alert you to an intrusion, and possibly scare away an intruder before you consider pyrotechnics (you don't want to set your chicken coop on fire do you? there's a lot of bird poop around that can be quite flammable whether you realize it or not)....

I changed my mind about making a remote detonator. Instead, I'll do remote monitoring. I don't need anyone to know where it is. Superfluous sounds would definitely attract attention. I need to assemble a module with a video camera for taking a photo. What microcontroller can you suggest for this?

I need to shoot a photo of 200 * 200 quality at a frequency of 25 frames per second (1 picture per minute)

That makes no sense. 25 frames per second is 1500 frames per minute.

Mike.

shoot = 1 sec/25. and 1 min for crypto
mc or raspberry pi, orange pi?
