Arduino Based Ethernet WebServer Practical Implementation

Making Ethernet Web Server with Arduino

Build your own IOT service! Collect sensor data and send it to a WebServer. In this article, we are going to create a webserver using the Arduino and the Ethernet shield. The Arduino Ethernet makes everything so easy that it looks like magic. The Arduino Ethernet Shield allows you to easily connect Arduino to the internet. This shield enables Arduino to send and receive data from anywhere in the world with an internet connection. This shield opens up endless amounts of...

Temperature Data Logger with SD Card

Temperature and Humidity Data Logger using Arduino

In this project, we are going to make a temperature and relative humidity data logger. Arduino is the brain of this project. DHT22 sensor is used for sensing temperature and relative humidity. Arduino Uno is programmed to read temperature, humidity values from DHT22 sensor and save it to a file in an SD Card. So whenever required we can take the SD Card for viewing data. Here we will take data from SD card and import it to excel to...

Temperature Controlled Fan using Arduino

Temperature Controlled Fan using Arduino

Here we are going to make a temperature controlled DC fan. DHT22 sensor is used to sense the room temperature and then we adjust speed of a DC fan/motor accordingly using PWM (Pulse Width Modulation). Arduino Uno is the heart of this project and a L293D driver IC is used to drive the DC fan/motor.

Components Required

Arduino Uno L293D Motor Driver IC DHT22 Sensor 16x2 LCD Display DC Fan/motor 9V Battery 10KΩ Potentiometer 220Ω Resistor Breadboard

Weather Station using Arduino - Web Server - IoT

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...

IoT Data Logger using Arduino and ESP8266

IoT Data Logger using Arduino and ESP8266

Today we are going to make an IoT WiFi data logger using Arduino, ESP8266 WiFi module and DHT22 temperature humidity sensor. Arduino is reading temperature and humidity sensed by DHT22 and sending it to an internet server using the ESP8266 WiFi module. Here we are using ThingSpeak as the internet server. ThingSpeak is an open source IoT application which can be used as an Internet or Intranet Server. It is providing HTTP API for data logging, location tracking, status updates...
