DS18B20Z+

The DS18B20Z+ is a 1-Wire® programmable resolution Digital Thermometer. The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with non-volatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire® bus that by definition requires only one data line (and ground) for communication with a central microprocessor. It has an operating temperature range of -55°C to +125°C and is accurate to ±0.5°C over the range of -10°C to +85°C. In addition, the DS18B20 can derive power directly from the data line (parasite power), eliminating the need for an external power supply. Each thermometer has a unique 64-bit serial code, which allows multiple thermometers to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many thermometers distributed over a large area.
