++
  RS485-BL has a Controllable +3V3 output, user can use this output to power external sensor.
  The +3V3 output will be valid for every sampling. RS485-BL will enable +3V3 output before all sampling and disable the +3V3 after all sampling.
++
  The +3V3 output time can be controlled by AT Command.
++**AT+3V3T=1000**
--(% style="color:#037691" %)**AT+3V3T=1000**

--
  Means set +3v3 valid time to have 1000ms. So, the real +3v3 output will actually have 1000ms + sampling time for other sensors.
