WSN-ESP8266

Some simple project of Single Hop WSN by using ESP8266/NodeMCU

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.

The Material you need for this Tutorial

2 Units of ESP8266 or Nodemcu.

2 Units of USB Type Micro B Cable.

2 Units of Sensors.

Software you need for this Tutorial

Thingspeak. Click here to register Thingspeak

Arduino IDE. Click here to download the Arduino IDE

You also need this library to be installed to get started

1. ESP8266/NodeMCU Library Please refer this guide
2. Thingspeak Library Please refer this guide
3. Any related Sensor Library (For Example if you using DHT11, then you may need to have DHT Arduino Library)

Before you start, Please make sure that you have found the Receiver MAC Address of the RECEIVER.

To communicate via ESP-NOW, you need to know the MAC Address of the RECEIVER. That’s how you know to which device you’ll send the information to. There's a folder named WSN_Get_MAC_Address_For_Receiver the Source code inside there is use to find the MAC Address of the RECEIVER. After you have upload the code please write the MAC Address acquired at any place for the next use, later you replace it with Receiver Code for the RECEIVER.
