DESCRIPTION
The DS18S20-PAR digital thermometer provides 9–bit centigrade temperature measurements and has an
alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18S20-PAR
does not need an external power supply because it derives power directly from the data line (“parasite
power”). The DS18S20-PAR communicates over a 1-Wire bus, which 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 +100°C and is accurate to ± 0.5 ° C over a range of –10°C to +85°C.
Each DS18S20-PAR has a unique 64-bit identification code, which allows multiple DS18S20-PARs to
function on the same 1–wire bus; thus, it is simple to use one microprocessor to control many
DS18S20-PARs distributed over a large area. Applications that can benefit from this feature include
HVAC environmental controls, temperature monitoring systems inside buildings, equipment or
machinery, and process monitoring and control systems.
