Sensors

Modbus baud rate : 4800 bauds

Byte 0: CO2 sensor or Noise sensor (Most Significant Byte)
Byte 1: CO2 sensor or Noise sensor (Least Significant Byte)

For instance, byte[0]: 0x82 and byte[1]: 0x02 -> 0x0282 = 642 (642ppm if it is CO2 sensor o 64.2dBA if it is a noise sensor)

Byte 2: PM2.5 sensor (Most Significant Byte)
Byte 3: PM2.5 sensor (Least Significant Byte)
Byte 4: PM10 sensor (Most Significant Byte)
Byte 5: PM10 sensor (Least Significant Byte)

For instance, byte[2]: 0x0F, byte[3]: 0x00, byte[4]:0x10 and byte[5]: 0x00 -> 0x000F = 15 (PM2.5: 15ug/m3) and 0x0010 = 16 (PM10: 16ug/m3)
