Description
The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile 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 DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s distributed over a large area.
For use with an Arduino you need to download the Dallas Temperature Control Arduino library and the OneWire Library.
