    FAQ
    ❯

    A laser PM sensor is a sensor that uses the principle of laser scattering to detect the concentration of suspended particles in the air (such as PM1.0, PM2.5, and PM10).

    ❯

    Laser PM sensors usually exist in the form of modules and can be connected to a microcontroller through a serial port (UART), I²C, or SPI interface. When installing, pay attention to keeping the air intake unobstructed, avoid being close to air vents, oil smoke, or high humidity areas, fix the sensor in a well-ventilated position, and ensure regular cleaning to avoid errors caused by dust blockage.

    ❯

    Laser PM sensors are widely used in indoor air quality monitoring equipment, environmental monitoring stations, industrial workshop dust monitoring, and other occasions. It is suitable for environments with high requirements for air particle detection accuracy, especially in real-time monitoring and intelligent control systems.

    Surprisingly Accurate and Easy to Use
    I bought this sensor to monitor air quality in my workshop, and it has worked better than expected. The readings respond quickly whenever I’m sanding wood or using sprays, which makes me trust the accuracy. Setup was simple, and it’s been running reliably for weeks now. Definitely a solid purchase if you care about indoor air quality.
