Ex:

000C01 || 0343 || 04E803 || 059001

00 0C01 => Set keepalive interval: 0x0C -> 12 (x 5min) = 60 min (Unit:5min),

Set Detection interval 0x01-> 1 (x 5min) = 5 mins

Note: 0 means no change (Unit: 5min)

03 43 => Buzzer alarm period in 3 seconds, enable CO2 and disable proximity

sensor: 0x43

04 E803 => Set CO2 threshold: 0x03E8 -> 1000 ppm (*Note: little-endian format.)

05 9001 => Set CO2 calibration value: 0x0190 -> 400 ppm (*Note: little-endian

format.)
