Homemade Fire Alarm Circuit

I made a fire alarm using a pressure switch extracted from a gas boiler and an Aluminum bottle.
The principle is that when a fire breaks out and heat is transferred to the aluminum bottle, the internal pressure rises.
There is no standby current, the battery can be used for a long time.

This is for educational purposes. It can be used to explain the principles of fire detectors.
