The NS18B20 is a high-precision 1-Wire digital thermometer chip designed for temperature measurement within a range of -55C to +125C. It offers configurable digital conversion accuracy and measurement speed via a configuration register. The device features a built-in 5-byte non-volatile storage for user-defined information, including high/low temperature alarms and configuration accuracy. It supports both parasitic and external power supply modes, with the parasitic mode drawing power directly from the data line. Each NS18B20 possesses a unique 64-bit serial number, enabling multiple sensors to be controlled by a single processor on a shared bus. This makes it suitable for distributed temperature monitoring and control systems.
