DESCRIPTION
The DS18S20 digital thermometer provides 9-bit Celsius temperature measurements and has an alarm
function with nonvolatile user-programmable upper and lower trigger points. The DS18S20
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 DS18S20 can derive power
directly from the data line (“parasite power”), eliminating the need for an external power supply.
Each DS18S20 has a unique 64-bit serial code, which allows multiple DS18S20s to function on the same
1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18S20s 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
Pin systems.
