Block Diagram of Wireless Sensor Network >In this tutorial we will make a project Wireless Sensor Network by using 2 Unit of ESP8266 or NodeMCU with 2 Sensors and Thingspeak as the IoT Platform.

Learn how to establish a Wi-Fi communication (HTTP) between two ESP8266 NodeMCU boards to exchange data without the need to connect to the internet (you don’t need a router).

In this IoT projects, I have shown you how to make the smart home with Google Assistant & Alexa using NodeMCU ESP8266 to control relays with voice commands and manual switches. I have used all the ...

As usual I’ll be using a NodeMCU board (I really did order a lot of them) which uses an ESP8266, but there’s no reason this would be difficult to achieve on an Arduino-based device.

This paper presents the design and implementation of an automatic crop irrigation system based on a NodeMcu ESP8266 microcontroller integrated with the Blynk platform. The system is designed to water ...

Have an ESP8266 development board such as the NodeMCU or Wemos D1? You’re currently reading Hackaday, so probably. Got an Android device kicking around? Also seems fairly likely. In that case… ...
