    FAQ
    ❯

    It can be used in air purifiers/air conditioners to trigger purification logic. It is used for real-time monitoring of dust concentration in the fresh air system, automatically adjusting the air volume or starting and stopping the filter module.

    ❯

    It needs to avoid direct light and high-frequency interference sources (such as motors). It is recommended to place it behind the ventilation duct or the equipment filter.

    ❯

    Low cost, fast response (power-on stability ≤8 seconds), and long life.

    indoor infrared dust sensor works nicely
    I needed a compact sensor for an indoor air quality project and this one fit the space well. The indoor infrared dust sensor provides stable readings and the response is quick enough for monitoring changes. Wiring was straightforward, though I checked the pin details carefully before connecting it. It has been running smoothly inside the device without any problems.
