3M SS Waterproof Temperature Sensor Probe - DS1820
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.
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 control systems
