Description
This command is to start THPL measurement, in order: air temperature, air humidity, atmospheric
pressure, illuminance, but the sensor will not reply to the measurement data immediately after
receiving this command, but the time required to reply the measurement data and the number
of measurements. To obtain measurement data, you must wait until the measurement is
completed, and then use the send data command “0D0!” to obtain it.

power consumption. After using "continuous measurement command 0R0!...0R9!", it will exit the
low power consumption state.
