Smoke alarms use ionisation of air by an alpha source. A small pellet of the isotope of Americium sets up a current of a few micro Amps across an air gap and this is monitored by the electronic circuit. When smoke enters the ionisation cell the current is reduced as the smoke particles neutralise the charged ions. The dip in current causes the alarm to sound.

How can you relate ionisation potential and ionisation energy?
Ionisation potential and ionisation energy are essentially the same concept - they both refer to the amount of energy required to remove an electron from an atom or molecule. The terms are often used interchangeably in practice.
