There are two graphics below. First one is measuring home temperature, and second one is for measuring home humidity. Put your mouse over these red points in the graphics to learn about the values in realtime. This project is made for understanding Internet of Things consept. When I am away from home, I can read the temperature. This project is a kind of IoT - Internet of Things example.
There is a picture below. On this picture, you can see that I am using Arduino UNO board and expantion shield. I used ESP8266 and this shield in order to make circuit can easily attached on Arduino UNO. Only 5V, and current WiFi connection are enough to run this circuit. I am using ThingSpeak cloud platform to store temperature and humidity datas.
