  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**
