Digital Temperature Sensor

The DS18B20 is a digital temperature sensor that communicates via a 1‑Wire bus. It provides 9‑ to 12‑bit Celsius temperature measurements with ±0.5°C accuracy from -10°C to +85°C. Key features include programmable alarm limits, non‑volatile memory, and parasitic power mode.

Specifications:

• Temperature Range: -55°C to +125°C

• Accuracy: ±0.5°C (-10°C to +85°C)

• Resolution: 9‑12 bit (0.0625°C max)

• Supply Voltage: 3.0V to 5.5V

• Interface: 1‑Wire®

Applications: Industrial controls, consumer electronics, HVAC, thermostats, and temperature‑monitoring systems.
