In this project we have used Arduino Uno with Ethernet shield w5100, temperature sensors ds18B20 and 4-channel relay board.
As an addition for easier connection sensors and relays, we have used sensor shield and screw shield, but you can connect them however you want.
SeeedStudio Grove Beginner Kit for Arduino programmed with Arduino Control Center, no wiring, soldering, integrated sensor modules with Seeeduino Lotus Arduino UNO compatible board, desktop, and web controllable.
It includes one Arduino compatible Board and 10 additional Arduino sensors. Unlike most kits, the Grove Beginner Kit for Arduino brings you the simplest way to get familiar with the Arduino world.
With Arduino Control Center you will create a visually controllable system fastest than you ever think it's possible, hosted on your home PC.
