DESCRIPTION

· The DS18S20 is a high-precision digital thermometer providing 9-bit Celsius temperature measurements.

· It features an alarm function with nonvolatile user-programmable upper and lower trigger points.

· Communicates over a 1-Wire bus, requiring only one data line and ground for microprocessor communication.

· Supports parasite power mode, eliminating the need for an external power supply.

· Each device has a unique 64-bit serial code, enabling multiple DS18S20s to operate on the same 1-Wire bus.

FEATURES

· Unique 1-Wire interface reduces port pin usage for communication.

· Measures temperatures from -55°C to +125°C with ±0.5°C accuracy from -10°C to +85°C.

· 9-bit resolution ensures precise temperature readings.

· No external components required for operation.

· Parasite power mode allows operation with only two pins (DQ and GND).

· Multidrop capability simplifies distributed temperature-sensing applications.

· Flexible user-definable nonvolatile alarm settings with alarm search command.

APPLICATIONS

· Thermostatic controls in HVAC systems.

· Industrial systems for temperature monitoring.

· Consumer products requiring temperature sensing.

· Thermometers for various applications.

· Thermally sensitive systems in equipment or machinery.

· Process monitoring and control systems.
