Product alarm principle

When the smoke enters the alarm, the light source scatters, the light receiving element feels the light intensity, and the received light intensity has a certain linear relationship with the smoke concentration. The alarm continuously collects, analyzes and judges field parameters. When the light intensity reaches a predetermined threshold, the alarm's red LED lights up and the buzzer alarm is activated. When the smoke in the environment where the alarm works is gone, the alarm will automatically return to normal working state.
