Working principle of smoke detector

The smoke alarm has an ion chamber inside, which can emit ionization and produce positive and negative ions when inside

1. The smoke alarm has an ion chamber inside, which can emit ionization and produce positive and negative ions when inside, and can move under the action of an electric field. If there is no fire, the current and voltage in the ionization chamber are relatively stable.
2. But if there is smoke indoors, it will interfere with the normal operation of electric particles, and the current and voltage will also change, which will disrupt this balance. The transmitter will emit an alarm signal and notify the receiving host, so the alarm signal will be transmitted.
