5°C over the typical range of -10°C to +85°C. The Arduino environment requires specific libraries to handle the complex 1-wire protocol and Dallas temperature calculations.
Building a Waterproof DS18B20 Temperature Probe for Arduino
The sketch begins by including the necessary library files and defining the pin number connected to the sensor's data line. The OneWire library manages the low-level communication over the single data line, while the DallasTemperature library abstracts the intricate commands needed to request temperatures and read the scratchpad memory.
Arduino Code Implementation Translating the hardware and library knowledge into functional code involves a few concise steps. Its operational range spans from -55°C to +125°C, with an accuracy of ±0.
