You didn't mention wires. And I think it's worth considering. Most probably your sensor is going to be connected to power plug (if it goes detached). So why not to situate mini-server (RPi-alike) nearby, with a sensor connected by wire?
- impostervt 10y agoNot sure I follow. The door sensor is going to be hanging on my daughter's door, and the alarm would be in my room, probably 40 ft away.
- andrey_utkin 10y agoWherever you place the sensor, it most probably needs power supply. Batteries die, so I'd go with plugging into power socket. Since we use a nearby (to daughter's door) power socket, we could insert _right_there_ a mini-PC to control the sensor (because sensor just senses, and you need some "digital brain" to do something with results of sensing). Then mini-PC could notify you in a lot of possible ways.
