# Air Conditioning Web Controlled by Arduino

> With this you can switch ON or OFF, your home's air conditioning system, checking the ambient temperature and humidity, and all this

Original author: MoniCris (source: https://www.instructables.com/Air-Conditioning-web-controlled-by-Arduino/)

## Components

- **Arduino Ethernet Shield** x 1 ([docs](https://docs.arduino.cc/retired/shields/arduino-ethernet-shield-without-poe-module))

## Article

**DETAILS**

## **Step 1: Hardware**

1. Arduino Mega

2. Ethernet shield

3. 5v(USB), 6v or 9v power plug for arduino

4. LAN ethernet cable

5. DHT22(or DHT11) sensor for temperature/humidity

6. Infra Red (IR) LED from a remote control or less than 1€ in electronics shop

7. temporary: an IR receiver

8. temporary: a breadboard with three wires

## **Step 2: Getting the Codes**

## **Step 4: Setting Up Router**

For this you need to refer to your router manufacturer and open the ports that arduino can be seen from outside.
If you have a dynamic IP, you must use a free service like noip.com or dyndns.org. With static IP, just open ports on router and use it.
