Digital Output: The DS18B20 provides a digital output, making it easy to interface with microcontrollers and other digital devices. It uses the One-Wire interface, a proprietary communication protocol developed by Maxim Integrated.
High Accuracy: This sensor offers high accuracy in temperature measurements. It has a temperature resolution of 0.0625°C, which allows for precise temperature monitoring.
Wide Temperature Range: The DS18B20 can measure temperatures in a wide temperature range, typically from -55°C to +125°C, making it suitable for a broad range of applications, including extreme temperature environments.
Multiple Sensors on a Single Bus: One of the notable features of the DS18B20 is the ability to connect multiple sensors to a single data bus. Each sensor has a unique 64-bit serial code, allowing multiple sensors to be addressed individually on the same bus.
Parasitic Power Mode: The DS18B20 can operate in a parasitic power mode, which means it can draw power from the data line without requiring a separate power supply pin. This simplifies the wiring and reduces the number of required connections.
Programmable Alarm Function: The DS18B20 includes programmable upper and lower temperature alarm functionality. It can trigger an alarm signal when the temperature crosses these set thresholds.
Nonvolatile Memory: The sensor includes nonvolatile memory for storing the user-defined configuration, such as temperature resolution and alarm settings.
