CDS - Cat Defense System (Arduino + Servo + Motion Sensor)

[MaKin]

Hey guys,

as our cat tries to drive us crazy for a while now and as my wife is pregnant and should get a little sleep as long as she can, I thought about building some kind of Cat Defense System consisting of a spray bottle filled with water, an arduino, a MG996R Servo and a HC-SR501 PIR motion sensor.

Will keep you updated. :)

@MaKin This seems to work very well: https://www.amazon.co.uk/PetSafe-Ssscat-PDT17-14118-Spray-Deterrent/dp/B00DUVJQRO
It produces a burst of compressed air, triggered by a motion sensor. Should be possible to MySensorize ;-)

Good to know but 40€, that is very much for a sensor can. :-1: And it's less fun. :D

You can always take the idea and DIY something similar ;-)

One Idea instead of a servo would be a solenoid. Seems to me that it would have a faster reaction time than a servo. You would just need one strong enough to pull the trigger on the spray bottle.

@Tetnobic yep, thanks. :)

Is there one you'd recommend?

@MaKin
I have not done this build, but if I had to do it I will try with this
The most complicated is to find the Raid Power Sprayer :-)
