Laser Dust Sensor Installation Method: The dust collection hole is the air inlet inside the sensor, which needs to keep good contact with the external air; the fan is installed at the air outlet inside the sensor. When the sensor is installed and working, must avoid strong airflow interference around the sensor; if it cannot be avoided, try to keep the external airflow direction perpendicular to the internal airflow direction of the sensor. When designing the detection cavity of the whole machine, the effective area of the sampling port of the sensor should be fully considered to ensure the smoothness...

Laser Dust Sensor Typical Output Characteristics: Fig10 Note: The picture shows the data comparison between the conventional ZH06 laser particle sensor and TSI8530 in the test environment. Abscissa : Testing time related parameters Ordinate : The concentration of particles in the test environment (with TSI8530 data as reference, unit: μg /m³, environmental resolution: 1μg/m³). Attentions: 1. It is forbidden to remove the shield cover of the sensor and the internal fixing screw of the sensor, because the shield cover of the sensor is connected with the internal power supply of the sensor through...

Laser Dust Sensor environment. The actual working environment should try to avoid oil&smoke environment, too large dust particles, high humidity environment, such as: kitchen, bathroom, smoking room, outdoor environment, etc. If it is used in such environments, corresponding protective measures shall be added to the user's equipment to prevent viscous particles or large particles from entering the interior of the sensor and forming accumulation in the interior of the sensor which will affect the performance of the sensor. (for example, in the working environment with floccules or fibers, the...
