Here’s the schematic you need to follow:Īfter installing the needed libraries, upload the following code to your Arduino board.
Normal mode: 3-wire connection is needed.You can use the preceding links or go directly to /tools to find all the parts for your projects at the best price! DS18B20 temperature sensor (one or multiple sensors) – waterproof version.
Arduino UNO – read Best Arduino Starter Kits. Here’s a list of parts you need to complete this tutorial To show you how the sensor works, we’ll build a simple example that reads the temperature from the DS18B20 sensor with the Arduino and displays the values on the Arduino Serial Monitor. Accuracy +/-0.5 ✬ (between the range -10✬ to 85✬)įor more information consult the DS18B20 datasheet. Operating temperature range: -55✬ to +125✬. Communicates over one-wire bus communication. Here’s a summary of the most relevant specs of the DS18B20 temperature sensor: The DS18B20 temperature sensor is also available in waterproof version. So, you can get temperature from multiple sensors using just one Arduino digital pin. This allows you to wire multiple sensors to the same data wire. The following table shows how you should wire the DS18B20 sensor to your Arduino board: DS18B20Īny digital pin (with 4.7k Ohm pull-up resistor)Įach DS18B20 temperature sensor has a unique 64-bit serial code. It can be powered by an external power supply or it can derive power from the data line (called “parasite mode”), which eliminates the need for an external power supply. This means that it just requires one data line (and GND) to communicate with the Arduino. 
The DS18B20 temperature sensor is a one-wire digital temperature sensor.
