The DS18B20-PAR+T&R is a 1 wire parasite-power digital thermometer in 3 pin TO-92 package. It provides 9 to 12bit centigrade temperature measurements and has an alarm function with non-volatile 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). It communicates over a 1 wire bus that requires only one data line and ground connections for communication with a central microprocessor. It has an operating temperature range of -55°C to +100°C and is accurate to ±0.5°C over a range of -10°C to +85°C. Each DS18B20-PAR has a unique 64bit identification code which allows multiple DS18B20-PARs to function on the same 1 wire bus. Thus, it is simple to use one microprocessor to control many DS18B20-PARs distributed over a large area. Typical applications include HVAC, environmental controls, temperature monitoring systems and process monitoring and control systems.
