Features: The DS18B20 is a high accuracy programmable digital single bus temperature measurement chip. The temperature sensor has a temperature range of -55C to +125C and a maximum resolution of 0.015C. The maximum error is 0.5C from -10C to +85C and 1.5C over the full temperature range. The user can choose the power supply mode and the parasitic power supply mode. The chip has a built-in non-volatile memory unit for storing user-defined information such as high and low temperature alarm thresholds, sensor node numbers, position information, and temperature calibration information. Single bus interface for distributed multi-node measurement.Simple to use, no additional devices required. Typical application:temperature monitoring, environmental monitoring, water temperature measurement, smart home appliances, smart agriculture. Each chip has a programmable ID serial number, which is convenient for networking users to set alarm values by themselves.
