NS18B20: 1-Wire Digital Thermometer NOVOSENSE DESCRIPTION NS18B20 is a high precision 1-wire bus system temperature measurement chip. The temperature range of the temperature sensor is -55 °C to +125 °C. The digital conversion accuracy and temperature measurement speed can be set through the configuration register according to user needs. NS18B20 has a built-in 5byte non-volatile storage unit for users to use. 3byte is used for high and low temperature alarms and configuration accuracy. In addition, 2byte is used to save user-defined information. The nonvolatile storage write cycle takes 10ms. The maximum error of the device is ±1°C over the full temperature range. NS18B20 has two working modes: parasitic power supply and external power supply, in which the parasitic power supply can be powered through the data line without external power supply. Each NS18B20 has a unique 64-bit serial number. Using a single bus interface allows multiple devices to hang on the same bus. Therefore, this feature can use a processor to control multiple NS18B20 sensors. NS18B20 is widely used in distributed temperature environment monitoring, temperature control and other systems.
