DALLAS 18B20 PDF

This feature can be a huge advantage when you want to control many DS18B20s distributed over a large area. To know how to read temperature from multiple DS18B20 temperature sensors, please check this tutorial out. As each DS18B20 has a unique bit DQ is 1-Wire Data Bus should be connected to a digital pin on microcontroller. VDD pin supplies power for the sensor which can be between 3. The connections are fairly simple.

There are many temperature sensors available in market like LM35, DHT11 etc but personally I like Dallas18B20 most of all, as it gives the most accurate result up to four decimal points.

It operates on single wire and sends all data through this wire. Another advantage of this wire is you can interface multiple sensors with a single data line. We will get the values in degree centigrade. Its not much difficult to interface 18B20 with arduino and also an Arduino library is also availble, using which you can quite easily interface 18B20 with Arduino.

Interfacing of Temperature Sensor 18B20 with Arduino As I explained earlier, it works on single wire and hence we are gonna need 1-wire library for Arduino along with 18B20 arduino library.

Download both of these libraries by clicking on the below buttons: After downloading the library, place it in the libraries folder of your Arduino Software. Now restart your Arduino software and you will find the Arduino folder in the Examples section.

Next we need to interface our sensor 18B20 with Arduino so design your circuit as shown in below figure: So, connect the sensor 18B20 with Arduino as shown in the above figure, connections are quite simple and are as follows: Pin 1 of 18B20 with GND Pin 2 of 18B20 with Pin 2 of Arduino. Add a pull up resistor of 4.
