Small README fix #8

Closed kanazir closed 4 years ago

kanazir commented 4 years ago

Hi,

on NodeMCU Preparation the README says that PMS7003 sensor should be powered from VIN pin of NodeMCU. But, that pin can't be used to power anything on v3 - VUSB should be used instead.

Can you fix it, please?

Hey, you most likely have the NodeMCU board with CH340 chip (that's the cheaper one 😄). That board is off in many ways, such as being incompatible with breadboards, the VIN issue you're having, the inferior serial-to-usb chip and the incompatibility with the 3D printed enclosure provided in this repo. The one linked in this README is the CP2012-based one, which doesn't have any of these issues.

Ah... I had one in my drawer for a long time so, I used it for the project, not thinking about its quality :smiley: Thanks!
