DS18B20-PAR Description
The DS18B20-PAR digital thermometer provides 9 to 12 bit centigrade temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20-PAR does not need an external power supply because it derives power directly from the data line (“parasite power”). The DS18B20-PAR municates over a 1-wire bus, which by definition requires only one data line (and ground)...
