It was used to test Arduino Mega2560 and Ethernet Shield W5100 (clone) for sensor data DHT11 and relay module.
DHT11 sensor information is sent to a local seridor within the Ethernet Shield. Access to information is made through a Web browser simply by typing, for example the address of the Ethernet (server) in the URL: http://192.168.0.99, which for example, I programmed this IP address, which is in range of my home network.
The assembly as you can see in the picture this means messy …: S but at this stage it is allowed … but important is to mount calmly observing the polarity, positive, negative, sensor connections, finally if leaving for the actual implementation is Legal leave everything organized in plastic box.
Here is a hint of a html page to read the display DHT11 sensor, which is in the Arduino code. When access is made by the browser address he will seek the server (Ethernet Shield) that will make the display of this HTML file, containing sensor reading the more the possibility to drive any load, through the buttons.
