    Dust sensor module wiring

    The figure above shows the pin definition of the dust sensor module. U5, U6, U7, and U8 are interfaces for the temperature and humidity sensor, CO2 sensor, PM2.5 sensor, and VOC sensor, respectively. The installation locations are in the four blue boxes in the figure above, where the solid line box refers to the installation on the front of the circuit board, and the dotted line box refers to the installation on the back of the circuit board. P2 and P3 are external interfaces, used for communication and host power supply, respectively. P5 is a 3PIN jumper cap interface for RS-485 long-distance communication.

    FAQ
    ❯

    In industrial or high-dust environments, it is advisable to add a dust cover or air filtration module to the sensor to prevent large particles from entering, which could cause obscuring or corrosion. At the same time, the working environment should be kept ventilated and dry.

    ❯

    Avoid airflow interference, prevent moisture and condensation, perform regular calibrations, and avoid vibrations.

    ❯

    Cost savings, one device replacing multiple standalone sensors. Data synergy, linked analysis of PM2.5 with temperature and humidity. Compact design suitable for embedded applications.
