Method and apparatus for calibrating particulate matter measurement value

A device for calibrating a particulate matter measurement value, comprising:

• a processor;
• and
• a memory configured to store instructions executable by the processor,
• wherein, the processor is configured to:
• when a current particulate matter measurement value is obtained, obtain a current temperature-humidity parameter;
• obtain a particulate matter measurement deviation value corresponding to the current temperature-humidity parameter from pre-stored particulate matter measurement deviation values corresponding to various temperature-humidity parameters according to the current temperature-humidity parameter, wherein the particulate matter measurement deviation value is obtained using a standard particulate matter variation curve corresponding to a standard temperature-humidity parameter, and the standard particulate matter variation curve is obtained by blowing dusts into an experiment box;
• calibrate the current particulate matter measurement value according to the particulate matter measurement deviation value corresponding to the current temperature-humidity parameter;
• obtain current position information;
• transmit the current position information to a target device, wherein the target device is configured to obtain the current temperature-humidity parameter according to the current position information;
• and
• receive the current temperature-humidity parameter sent from the target device.
