As a place for daily rest and relaxation, maintaining good air quality in the bedroom is vital for health. Dust sensors, as essential equipment for detecting fine particulate matter in indoor air, directly affect our perception of air quality through their accuracy and reliability.

So, is it necessary to calibrate the bedroom dust sensor periodically?

The answer is: Yes.

During use, a dust sensor's measurement precision may deviate due to environmental factors and sensor aging. Therefore, regular calibration is required to ensure the accuracy of measurement data.

Generally, it is recommended to calibrate the dust sensor every three months. If the environment is harsh—such as high dust concentrations or frequent oil fumes—the calibration frequency should be increased to once a month.

There are two main methods for calibrating dust sensors:

Calibration with Standard Dust: This involves releasing a known concentration of standard dust into a closed space and measuring it with the sensor to calculate the deviation.

Calibration with Professional Instruments: This method uses specialized calibration equipment to adjust the sensor.

Important notes for calibration:

● Read the manual carefully and follow the instructions before starting.

● Perform calibration in a relatively clean space free of dust pollution.

● Record the calibration results for future reference.

To extend the sensor's lifespan, avoid extremely high-dust environments, clean the sensor housing regularly to prevent blockages, and avoid exposure to high temperatures or humidity.
