ESP8266 Floor mat sensor alarm

Today a picture of an alarm step mat (Conrad 751913 bought some years ago)  with, recently added, a long wire and a connector.

The floor mat is somewhere under a carpet in my house. The connector is plugged in a ESP8266 module.
This is not a detailed project, only for inspiration and a message to inform you that my carpet is upgraded to an IOT device.

In the first version ESP8266 GPIO pins are connected to

- Mat sensor line

- Security / tampering wire (from cable, mat) 

- Buzzer (local alarm; Disadvantage this reveals where the module is hidden)

- Shock/Vibration/Tilt sensor (detect moving or tampering of the ESP8266 module) 

Perhaps later i add:

- IR sensor for infrared remote control (switch it on/off or "panic button signal"). Current only by Wifi / Smartphone)

- Tampering (opening of the ESP8266 module if this is in a more permanent 'safe" box) 

- External power sensor.  If external power is missing the module runs on backup power. If the module knows this it can react ( Send message , sound buzzer)

- Panic button (this also reveals the module)
