The default communication mode is initiative uploading mode. 2. Take an example to explain calculate method: Receiving the following data frames: No. 0 1 2 3 4 5 6 7 8 9 10 11 Data 0x42 0x4D 0x00 0x14 0x00 0x54 0x00 0x6E 0x00 0x7C 0x00 0x54 No. 12 13 14 15 16 17 18 19 20 21 22 23 Data 0x00 0x6E 0x00 0x7C 0x00 0x00 0x00 0x00 0x00 0x00 0x03 0x1F Check value= 0x42+0x4D+0x00+0x14+0x00+0x54+0x00+0x6E+0x00+0x7C+0x00+0x54+0x00+0x6E+0x00 +0x7C+0x00+0x00+0x00+0x00+0x00+0x00 = 0x031F High 8 bits 0x03 is in 23th byte of data frame, low 8 bits 0x1F is in 24th byte of data frame. PM1.0 value=0x00*256+0x54=84ug/m3 PM2.5 value=0x00*256+0x6E=110ug/m3 PM10 value=0x00*256+0x7C=124ug/m3 The range for PM1.0, PM2.5 and PM10 are all 0-1000ug/m3. |
