HELP! Grove pm2.5 sensor HM3301 + SD card

Hi everybody, I'm noob. I’ve to record data from the dust sensor and record it on an SD card. Differently from other sensors i cannot do that easily using the command dataFile.print() for the variable that was printed on the serial monitor [Serial.print()] due to the codification that i don’t understand.

Sombody can help me?
