DS18B20 1-Wire Digital Thermometer - (AD2564)

Description:

The DS18B20 is a digital thermometer that provides 9-bit Celsius temperature measurement and features a user-programmable alarm function. It is non-volatile with high and low limit trip points. The DS18B20 communicates over a single-wire bus and therefore requires only one data line to communicate with a central microprocessor. It has an operating temperature range of -55°C to +125°C with an accuracy of ± 0.5°C over the -10°C to +85°C range. In addition, the DS18B20 can derive power directly from the data line ("parasitic power"), eliminating the need for an external power supply.
