Hello friends ! In this article, we will talk about what is ESP8266, how this wifi module works. We will also measure temperature and humidity with Arduino using this module and send the data to ThingSpeak. Let's have fun and learn 🙂
What's in the article? What is ESP8266 Wifi Module? What kind of projects can I do using this module? Is it possible to directly encode the processor inside the ESP8266 without using Arduino? Let's Learn How To Adjust Our Data To See Anywhere You Have Internet Using Arduino Using ESP8266
What is ESP8266 Wifi Module? What kind of projects can I do using this module?
ESP8266 is a WiFi module. With this module, it is possible to connect to wireless networks and to set up a wireless access point. Since the module has its own processor, I / O (input / output) pins on it can be used. This means that we can do projects with the module without Arduino and any similar microcontroller 🙂
Materials needed:
Arduino UNObreadboardESP8266 Wifi ModuleDHT11 Temperature and Humidity SensorSoil Moisture sensorMale-to-male jumper cableAfter determining the materials we will use in the application, let's set up our circuit as follows:
We can write the required Arduino code. You can access the DHT11 library here.
I explained how to use thingspeak in my previous article, but now we need to open field 1 field2 and field 3, we opened field 1 and field 2 in my previous article, now let's go to the settings and activate field 3 then copy our write api key from the api keys.
