DS18B20 Temperature Sensor Module

introduction

This breakout uses the DS18B20 1-Wire digital temperature sensor from Maxim IC. It can Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each

sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus. This is a wonderful part that is the corner

stone of many data-logging and temperature control projects.

Features

• 3.0-5.5V input voltage
• Waterproof
• -55°C to+125°C temperature range
• ±0.5°C accuracy from -10°C to +85°C
• 1 Wire interface

Usage

#include <DallasTemperature.h>
DallasTemperature tempSensor; // You may instantiate as many copies as you require.
void setup(void) {
 Serial.begin(9600);
 tempSensor.begin(12); // Data wire is plugged into port 12 on the Arduino
 Serial.println("Dallas Temperature IC Control Library 1.0. Miles Burton");
}
void loop(void) {
   // Ask the library whether the device is valid
   switch(tempSensor.isValid())
   {
       case 1:
           Serial.println("Invalid CRC");

tempSensor.reset(); // Attempts to redetect IC return;

       case 2:
           Serial.println("Not a valid device");

tempSensor.reset(); // Attempts to redetect IC

      return;
   }
 Serial.print(tempSensor.getTemperature());
 Serial.print("C");
 Serial.println();
 Serial.print(DallasTemperature::toFahrenheit(tempSensor.getTemperature()));   Serial.print("F");
 Serial.println();
