Does NodeMCU have WiFi?

NodeMCU can run in one of four WiFi modes: Station mode, where the NodeMCU device joins an existing network. Access point (AP) mode, where it creates its own network that others can join. Station + AP mode, where it both creates its own network while at the same time being joined to another existing network.

How does NodeMCU store data in cloud?

Here are the main steps:

  1. Click on ‘New Sensor’ to create a communication channel with unique ID and Api Keys. Give a name and description to your sensor.
  2. Add a module for the data you will be plotting.
  3. Copy down the Api Key In value. We will use in the ESP8266 code later.

How do I send data to cloud using NodeMCU?

Running

  1. Code upload. Connect the NodeMCU to the PC via USB and select the 115200 port in the Arduion IDE. Use the upload button to compile the sketch and upload it to the device.
  2. Open Arduino monitor window to view data reporting.

Can we connect NodeMCU to my computer?

Step 1: Connect your NodeMCU to your computer You need a USB micro B cable to connect the board. Once you plugged it in, a blue LED will start flashing. If your computer is not able to detect the NodeMCU board, you may need to download the driver on this page.
