Thought you guys might like this.
I have mice in my attic, and it's a pain going up there as it makes a huge mess when I open the attic hatch, so I came up with a mouse trap that triggers an alarm notification. It's actually very simple. The arduino device is just a generic input retriver that the monitoring app running on my server queries for data. I will be adding other stuff on this later on like smoke detectors, water sensors etc...
The server rack with DIN rail on top, where everything connects to
Terminal block in closet for the traps to connect to (gives me a test point to ensure the system is working)
The traps. Yes that is an RJ45 port on a mouse trap.
They're setup in groups of 2 in series. I only need to go up the attic when the 3 sets trip.
It monitors power too.
There's also pull down resistors on the junction point in the closet, they arn't in that pic. They used to be on the trap itself but when I disconnect the ethernet cable then it takes them out of the picture on I get lot of trip/recover alarms, so now they are before the traps. The ethernet port makes it easy to disconnect/reconnect.
So far I have not caught any with this new system, but I'm almost looking forward to because I'll be sitting at work or something and get the email pop up which is pretty awesome.
The power outages are good to know too, my server stuff is good for about 4 hours on batteries so I need to shut stuff down if a long outage happens. Rare, but it happens.
The EnviroState program is something I've been working on, it's basically equivalant to apps like Nagios, Pandora etc but is simplified. I will probably release it to public at some point when I deem it production worthy.
