Smart Smoke Detector Wifi Smoke Sensor with CE, ROHS Certificate

Smoke detectors achieve fire prevention by monitoring the concentration of smoke. Ionic smoke sensors are used internally in smoke detectors. Ionic smoke sensors are technologically advanced, stable, and reliable sensors that are widely used in various fire alarm systems, with performance far superior to gas sensitive resistor type fire alarms.

It has a radioactive source of americium 241 inside the internal and external ionization chambers, and the positive and negative ions generated by ionization move towards the positive and negative electrodes under the action of an electric field. Under normal circumstances, the current and voltage of the inner and outer ionization chambers are stable. Once smoke escapes from the ionization chamber. If it interferes with the normal movement of charged particles, the current and voltage will change, disrupting the balance between the internal and external ionization chambers. Therefore, the wireless transmitter sends a wireless alarm signal to notify the remote receiving host and transmit the alarm information.
