DS18B20 Digital Temperature Sensor – 1-Wire, TO-92, −55 to +125 °C

Accurate digital temperature sensorcommunicating through a 1-Wire interface – only one microcontroller data pin is required.

Known for its reliability, easy wiring and accuracy, the DS18B20 is widely used in Arduino and ESP32 projects, for measuring the temperature of liquids, soil and air and in smart homes.

🔧 Specifications:

• Temperature measurement range: −55 °C to +125 °C

• Accuracy: ±0.5 °C (−10 °C to +85 °C)

• Supply voltage: 3.0 V – 5.5 V DC

• Resolution: 9 to 12 bits (configurable)

• Interface: 1-Wire (multiple sensors on one data line)

• Package: TO-92 (breadboard-friendly)

• Each sensor has a unique 64-bit ID – ideal for multi-sensor buses.

📦 Applications:

• Measuring water, soil and air temperature

• Smart thermostats and heating systems

• Embedded and IoT systems (Arduino, ESP32, STM32…)

• Temperature monitoring for batteries, servers and food storage
