XBLW DS18B20(XBLW)

The DS18B20 digital thermometer provides temperature measurement with a resolution of 9 to 12 bits, and can achieve lower and upper temperature limit alarms through programmable non-volatile storage units. DS18B20 uses a single bus protocol to communicate with the upper computer, requiring only one signal line and one ground line. Its temperature measurement range is -55℃ ~ +125℃. The testing accuracy within the range of -10℃ ~ +70℃ can reach ± 0.4℃. In addition, it can also operate in parasitic mode, directly supplying power to the chip through signal lines without the need for additional power supply. Each DS18B20 has a globally unique 64 bit serial number, which allows multiple 18B20s to be connected in series on the same single bus for networking. With just one processor, multiple DS18B20s distributed over a large area can be controlled. This networking method is particularly suitable for HVAC environmental control, building, equipment, grain temperature measurement, industrial temperature measurement, and process monitoring and control applications.
