The working of zero-crossing detector is to detect the transition of a signal waveform from positive and negative, providing a narrow pulse that coincides exactly with the zero condition.
Zero crossing is commonly used in mathematics and electronics. Its when the mathematical function changes represented by crossing at an axis.

i think they operate with solenoids (light detectors).
Your smoke detector may beep every 30 seconds if the battery is low or if there is a malfunction in the detector. It is important to replace the battery or check for any issues to ensure the detector is working properly.
Two sine waves, one with zero crossing at 30 degrees, the other with zero crossing of 45 degrees, have a relative phase angle of 15 degrees. Simply subtract the two angles from each other.
Your smoke detector may beep once to indicate a low battery or a malfunction. It is important to address this issue promptly to ensure the detector is working properly in case of a fire.
zero demodulated signal, which occurs for phase angle equal to + or - 90degrees, represent Quadrature Null Effect of the coherent detector.
