DESCRIPTION
The DS1822 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 DS1822
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
±2.0°C over the range of –10°C to +85°C. In addition, the DS1822 can derive power
directly from the data line (“parasite power”), eliminating the need for an external power supply.
Each DS1822 has a unique 64-bit serial code, which allows multiple DS1822s to function on the same 1–
wire bus; thus, it is simple to use one microprocessor to control many DS1822s 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.
