Remote Smoke Alarm Project May 2021, karl grabe

Modify a Smoke alarm to have a remote buzzer and/or microcontroller interface.

Project Instructions, Arduino code etc.

On as a featured project.


  1. Alert occupant to an alarm that’s triggered in a distant room/garage/attic

  2. Allow multiple smoke alarms and buzzers to be connected together with a two core cable.

  3. Monitor alarms from a microcontroller (e.g. it could send a text if the house is unoccupied)

  4. Activate the buzzer from the microcontroller (it may be monitoring e.g. water tank level)
