milesburton/Arduino-Temperature-Control-Library: 🌡️ Arduino library for interfacing with Maxim temperature sensors like DS18B20, DS18S20, and MAX31850. 🔌 Supports multiple sensors, ⚡ asynchronous operation, and 🎯 configurable resolution for precise temperature monitoring.

A robust and feature-complete Arduino library for Maxim Temperature Integrated Circuits.

• DS18B20
• DS18S20 ( ⚠️ Known issues with this series)
• DS1822
• DS1820
• MAX31820
• MAX31850

1. Open Arduino IDE
2. Go to Tools > Manage Libraries...
3. Search for "DallasTemperature"
4. Click Install
5. Also install the required "OneWire" library by Paul Stoffregen using the same method

1. Download the latest release from GitHub releases
2. In Arduino IDE, go to Sketch > Include Library > Add .ZIP Library...
3. Select the downloaded ZIP file
4. Repeat steps 1-3 for the required "OneWire" library

1. Hardware Setup

   • Connect a 4k7 Ω pull-up resistor between the 1-Wire data line and 5V power. Note this applies to the Arduino platform, for ESP32 and 8266 you'll need to adjust the resistor value accordingly.
   • For DS18B20: Ground pins 1 and 3 (the centre pin is the data line)
   • For reliable readings, see pull-up requirements in the DS18B20 datasheet (page 7)

2. Code Example

   #include <OneWire.h>
   #include <DallasTemperature.h>
   
   // Data wire is connected to GPIO 4
   #define ONE_WIRE_BUS 4
   
   OneWire oneWire(ONE_WIRE_BUS);
   DallasTemperature sensors(&oneWire);
   
   void setup(void) {
     Serial.begin(9600);
     sensors.begin();
   }
   
   void loop(void) { 
      sensors.requestTemperatures(); 
      
      delay(750); 
      
      float tempC = sensors.getTempCByIndex(0);
      Serial.print("Temperature: ");
      Serial.print(tempC);
      Serial.println("°C");
      delay(1000);
   }

• Multiple sensors on the same bus
• Temperature conversion by address (getTempC(address) and getTempF(address))
• Asynchronous mode (added in v3.7.0)
• Configurable resolution

You can slim down the code by defining the following at the top of DallasTemperature.h:

#define REQUIRESNEW      // Use if you want to minimise code size
#define REQUIRESALARMS   // Use if you need alarm functionality

Visit our Wiki for detailed documentation.

If you want to contribute to the library development:

The project includes a development container configuration for VS Code that provides a consistent development environment.

1. Prerequisites

   • Visual Studio Code
   • Docker
   • VS Code Remote - Containers extension

2. Development Commands Within the dev container, use:

   • arduino-build - Compile the library and examples
   • arduino-test - Run the test suite
   • arduino-build-test - Complete build and test process

   Note: Currently compiling against arduino:avr:uno environment
