High quality relay output smoke detector working principle

The alarm adopts photoelectric sensor designed with special structure and MCU with reliable performance, which can effectively detect the smoke generated in the initial smoldering stage or after the generation of fire. When smoke into the alarm system, make the light scattering, accept element feel light intensity, the received light intensity and smoke concentration have certain linear relationship, the alarm parameters on site constantly gathering, analysis, and judgment, when confirm the intensity of light field data reaches the threshold, the alarm of the red LED lights up, and start the buzzer alarm. When the smoke in the working environment disappears, the alarm will automatically return to the normal working state.
