主要特征

  • Unique 1-Wire Interface Requires Only One Port Pin for Communication
  • Derives Power from Data Line ("Parasite Power")—Does Not Need a Local Power Supply
  • Multi-Drop Capability Simplifies Distributed Temperature Sensing Applications
  • Requires no External Components
  • ±0.5°C Accuracy from -10°C to +85°C
  • Measures Temperatures from -55°C to +100°C (-67°F to +212°F)
  • 9-Bit Thermometer Resolution
  • Converts Temperature in 750ms (max.)
  • User-Definable Non-Volatile Temperature Alarm Settings
  • Alarm Search Command Identifies and Addresses Devices Whose Temperature is Outside of Programmed Limits (Temperature Alarm Condition)
  • Software compatible with the DS1822-PAR
  • Ideal for Use in Remote Sensing Applications (e.g., Temperature Probes) That do not Have a Local Power Source

应用/用途

  • 远端检测应用

描述

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.
