Arduino Weather Station Web Server

In this tutorial we are going to make a weather station that will tell us temperature, humidity and heat index of a particular location. It will show these values in a web browser. You can monitor these data by entering the IP address in a mobile, computer or any other device which supports a web browser.This project is done using Arduino Uno, ESP8266 and DHT22 sensor. DHT22 sensor will read temperature and humidity information. ESP8266 WiFi module is used to establish network communication. Arduino is the core of this project which will read data from DHT22 sensor and sending it to a browser whenever a request is received. Arduino + ESP8266 is programmed to act as a web server.It uses digital signal collecting technique and humidity sensing technology. It’s sensing elements are connected with an 8-bit microcontroller. DHT sensors are small in size, consumes low power and has the long transmission distance using one wire bus (20m).DHT22 sensor consists of two sections, one for humidity sensing (capacitive humidity sensor) and another for temperature sensing (thermistor). The microcontroller inside the sensor reads both relative humidity and temperature from respective sensors. Then sends it via the output pin after converting to digital format.
