DS18B20 ,1-Wire Digital Temperature Sensor - Programmable Resolution, -55°C to +125°C

The DS18B20 1-Wire Digital Temperature Sensor offers accurate temperature sensing with a wide range of applications, including industrial systems, consumer products, HVAC systems, and more. This sensor can measure temperatures from -55°C to +125°C with a programmable resolution of 9 to 12 bits, ensuring flexibility in various environments. One of the key benefits of this sensor is its unique 1-Wire interface, which allows for easy connection to a microcontroller or other digital systems using just one data line.

It eliminates the need for an external power source as it can be powered directly from the data line, making it highly efficient and easy to integrate into compact designs. With a ±0.5°C accuracy between -10°C and +85°C, it is ideal for applications requiring precision and reliability. The DS18B20 also features alarm search commands, enabling it to identify and address devices whose temperature is outside programmed limits, making it highly functional for real-time monitoring and control systems.

• Wide Temperature Range: Measures temperatures from -55°C to +125°C (-67°F to +257°F), providing versatility for industrial, commercial, and domestic applications.
• Programmable Resolution: The resolution can be set from 9 to 12 bits, allowing precise measurement and flexibility based on application needs.
• 1-Wire Interface: Simple communication with only one data line required for communication, reducing the complexity of wiring and installation.
• Accuracy: Provides high accuracy of ±0.5°C in the range of -10°C to +85°C, making it reliable for critical applications.
• Parasite Power Mode: The DS18B20 can operate without an external power source by using power drawn from the data line, allowing easy and flexible integration into low-power systems.
• Multiple Devices on One Bus: Supports multi-drop capability, meaning several DS18B20 sensors can share the same data line, useful for systems monitoring multiple locations.
