Interfacing a DS1624 temperature sensor to an Arduino Uno

In this example we will connect a Ds1624 temperature sensor to an Arduino Uno, lets dive in and look at some information about this sensor

The DS1624 consists of two separate functional units: a 256-byte nonvolatile E² memory and a direct-to-digital temperature sensor.

The nonvolatile memory is made up of 256 bytes of E² memory. This memory can be used to store any type of information the user wishes. These memory locations are accessed through the 2-wire serial bus.

The direct-to-digital temperature sensor allows the DS1624 to measure the ambient temperature and report the temperature in a 12-bit word with 0.0625°C resolution. The temperature sensor and its related registers are accessed through the 2-wire serial interface.

Features

• Reduces Component Count with Integrated Temperature Sensor and Nonvolatile E² Memory
  • Measures Temperatures from -55°C to +125°C in 0.0625°C Increments
  • ±0.5°C Accuracy from 0°C to 70°C
  • 256 Bytes of E² Memory for Storing Information Such as Frequency Compensation Coefficients
  • No External Components
• Easy-to-Use 2-Wire Serial Interface
  • Temperature is Read as a 12-Bit Value (2-Byte Transfer)
• Available in 8-Pin SO and DIP Packages

Connection

This is an I2C device – it is safe to be powered from a 5v source

Code

I downloaded and imported the following library – https://github.com/bluemurder/DS1624

The code below is the default example which works perfectly

[codesyntax lang="cpp"]

#include <DS1624.h>

// Sensor presents all address pins connected to ground
DS1624 ds1624(0x00);

void setup()
{ 
// Begin serial connection at 9600 baud
Serial.begin(9600);
}

void loop()
{
float temperature;
bool valid;

// Get current temperature
ds1624.GetTemperature(temperature, valid);

// Print it
Serial.println(temperature);

// Wait a while
delay(1000);
}

[/codesyntax]

Testing

Open the serial monitor and you should see the following type of readings – which of course will vary depending on your environment
