1 – Trigger Event, 0 – Keep-Alive
RFU
1 – Temperature and humidity​ ​ s ensor,
0 – IAQ Sensor
1 - Temperature status is changed ( 2℃ delta)
1 - RH status is changed (5% RH deltas)
1 - IAQ status is changed (25 IAQ index)
RFU
unsigned value ν, range 1 – 14;
battery voltage in V = (25 + ν) ÷ 10.
RFU
unsigned value τ, range 0 – 127;
temperature in °C = τ - 32.
RFU
measurement range -32 to 95°C
unsigned value in %, range 0-100.
RFU
Estimation of the CO2 level in ppm. The
sensor does not directly measure CO2，but
derives this from the average correlation
between VOCs and CO2 in human's exhaled
breath.
