What did you see in the hotel room?

Smoke sense is actually another name for smoke detector or smoke alarm. Smoke detectors can prevent fire by monitoring the concentration of smoke. The smoke detector adopts ion smoke sensor. Ion smoke sensor is a kind of sensor with advanced technology and stable and reliable work, which is widely used in various fire alarm systems, and its performance is far superior to gas-sensitive resistance fire alarm.

It has radioactive source americium 24 1 in the inner and outer ionization chambers, and the positive and negative ions generated by ionization move to the positive and negative electrodes respectively under the action of electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once the smoke escapes from the ionization chamber outside and interferes with the normal movement of charged particles, the current and voltage will change, destroying the balance between the ionization chamber inside and outside, so the wireless transmitter sends out a wireless alarm signal to inform the remote receiving host and transmit alarm information.
