Smart smoke detector

Working Principle
The alarm utilizes a photoelectric sensor with a special structural design combined with a reliable MCU to effectively detect smoke generated during the initial smoldering stage of a fire or thereafter. When smoke enters the alarm, it causes scattering of the light source, and the light receiving element detects the light intensity. The received light intensity has a certain correlation with the smoke concentration. The alarm continuously collects, processes, and judges on-site parameters. When it is confirmed that the light intensity of the on-site data reaches a preset threshold, the red LED of the alarm lights up, and the buzzer is activated to sound the alarm. When the smoke in the environment where the alarm is operating dissipates, the alarm automatically returns to its normal working state.
