Typical Applications

• Fish tanks: Water temperature monitoring
• Hot water systems: Temperature control
• Farms: Monitoring temperature in animal watering vessels
• Weather stations: Measuring outdoor temperature

Connection and Programming

It is typically connected to a microcontroller unit (like Arduino). Proper operation requires a 4.7 kilo-ohm pull-up resistor between the data cable and the power source.Common Arduino libraries used for DS18B20 are OneWire and DallasTemperature to facilitate sensor reading and configuration.
