This paper demonstrates the efficient use of Internet of Things for the traditional agriculture. It shows the use of Arduino and ESP8266 based monitored and controlled smart irrigation systems, which ...

This project demonstrates how to control four relays using an ESP8266 (NodeMCU) and the Arduino IoT Cloud. The relays can be toggled locally via physical switches or remotely using a cloud-based ...

ESP8266 transceiver is used as a standalone microcontroller as well as a WiFi module with other microcontrollers. Explore here the DIY tutorials and projects based on ESP8266 WiFi module.

To use ESP8266 with Arduino, select the Board: "Arduino/Genuino Uno" and change it to "NodeMCU 1.0 (ESP-12E Module)" or other ESP8266 modules based on your hardware.

Here, we are using a 4 relay module because we will only control four appliances. If you want to automate a different number of appliances, you can use a different relay module. There are many relay ...

In conclusion, the Modbus 2-channel 5V relay module is a very useful device for making something Modbus compatible. I found the module relatively straightforward to use, and it seems to do a good job ...

In this tutorial, we are going to set up the NodeMCU-ESP8266 with the Arduino Cloud IoT. To test it out, we will send DHT11 sensor data from the board to the cloud, and set up a switch that can ...

So, connect TX of ESP8266 to Pin 2 of Arduino and RX of ESP8266 to Pin 3. Since, ESP8266 cannot tolerate 5V, the TX of Arduino (pin 3) is first level shifted using two resistors (1 KΩ and 2.2 KΩ) and ...
