About this product
The DS18B20 is a digital temperature sensor with a 1-Wire interface, so several sensors can share a single data pin. It reports temperature in degrees Celsius with 9 to 12-bit resolution across -55 °C to +125 °C, with ±0.5 °C accuracy, and each device has a unique 64-bit serial code. It is widely used in data-logging and temperature control projects.
