KEEP THE BURGLARS AWAY WITH SOME PI
ten years ago, we never imagined we would be able to ward off burglars with Pi. However, that is precisely what [Nick] is doing with his Raspberry Pi house safety and security system.
We like how, instead of using a common siren, [Nick] utilized his existing stereo system to play a customized audio data that he created. (Oh the possibilities!) exactly how numerous off the shelf alarm systems can you do that with?
The Pi is the brains of the operation, running an open source software application program called house Assistant. If any type of of the Z-Wave sensors in his home are triggered while the alarm system is armed, the system begins taking a number of actions. The stereo system is turned on via IR so that the digital alarm audio data can be played. Lights flash on as well as off. An IP video camera takes a number of snapshots as well as emails them to [Nick].
Home assistant didn’t really have the capability to send images in an email inline at the time that [Nick] was putting together his system. What did [Nick] do about that? He wrote some code to provide it that ability, as well as submitted it through GitHub. That new code was put into a later version of the program. Ah, the charm of open source software.
Perhaps the most essential part of this job is that there were steps taken to assist keep the wife-approval element of the system on the positive side. For example, he configured one of the scripts so that even if the alarm is tripped several times in succession, the alarm won’t play over itself repeatedly.
This isn’t [Nick’s] very first time being featured here. check out one more job of his which involves a couple of Pi’s communicating with each other via lasers.
