Temperature with DS18B20

It's a small project about temperature monitoring. I used a DS18B20 digital device to get the temperature. The device uses OneWire protocol. You need only an Arduino board, a DS18B20 and a 4.7KOhm resistor and a breadboard. If you have a display shield for the Arduino that's a plus.

Step 1 What you have to know about DS18B20

The device is communicating on one common bus. It means that you can connect several devices. We use only two pins on the device to connect them to the Arduino board. We need two libraries in the sketch: OneWire and DallasTemperature .

So we must include these libraries.

can this project be used for different types of sensors like temp,press,humidity etc..?

Yes, sure. As it is based on Arduino, many sensors can be used easily. You can start here: http://arduino.cc/playground/Main/InterfacingWithHardware#presssens
