DS18B20 temperature sensor programmable digital thermometer

DS18B20 is a high-precision single-bus temperature measurement chip. The temperature sensor ranges from -55℃ to +125℃; The precision of digital conversion and the speed of temperature measurement can be set by configuring the registers according to the needs of users. The chip has a built-in 4byte non-volatile memory unit for user use, 2byte for high and low temperature alarm, and another 2byte for storing user-defined information. The maximum error is ±0.4° C in the range of -10 ° C to +85 ° C.
The user can choose the power supply mode and the parasitic supply mode independently. The single-bus interface allows multiple devices to be attached to the same bus, which makes the DS18B20H also very convenient for deploying distributed temperature acquisition systems.
