++Notice: Different I2C sensors have different I2C commands set and initiate process, if user want to use other I2C sensors, User need to re-write the source code to support those sensors. SHT20 code in LSN50 will be a good reference.

Because the BAT pin is always open. If the external sensor is of high power consumption. the battery of SN50v3-LB will run out very soon.
--The S31x-LB uses OTAA mode and below frequency plans by default. If user want to use it with different frequency plan, please refer the AT command sets.

++SN50v3 will enable +5V output before all sampling and disable the +5v after all sampling.

++The 5V output time can be controlled by AT Command.

++**AT+5VT=1000**
++
++Means set 5V valid time to have 1000ms. So the real 5V output will actually have 1000ms + sampling time for other sensors.
