DS18B20+

The DS18B20+ is a digital temperature sensor produced by Maxim Integrated (now Analog Devices). It is well-known for its high accuracy, simple single-wire interface, and wide temperature measurement range. Here are its main features and specifications:

1. Temperature Measurement Range: -55°C to +125°C
2. Accuracy: ±0.5°C (within the -10°C to +85°C range)
3. Resolution: Adjustable from 9 to 12 bits
4. Interface: 1-Wire communication protocol, requiring only one data line for communication with a microcontroller, and it can be powered through parasitic power (no external power supply needed).
5. Power Supply Voltage: 3.0V to 5.5V
6. Data Transfer Speed: Up to 16.3 kbps
7. Unique 64-Bit Serial Number: Each sensor has a unique serial number, allowing multiple sensors to be connected on the same bus, which is convenient for multi-point temperature monitoring.
8. Package Options: TO-92, SOIC-8, and leaded versions, suitable for various applications.

The DS18B20+ is widely used in consumer electronics, environmental monitoring, industrial temperature control, home appliances, and other applications requiring precise temperature measurement.
