The DS18B20 digital thermometer provides 9-bit to 12-bit Celsius temperature measurements and has an alarm function with nonvolatile user-programmable upper and lower trigger points. The DS18B20 communicates over a 1-Wire bus that by definition requires only one data line (and ground) for communication with a central micro-processor. In addition, the DS18B20 can derive power directly from the data line (?parasite power?), eliminating the need for an external power supply.

Each DS18B20 has a unique 64-bit serial code, which allows multiple DS18B20s to function on the same 1-Wire bus. Thus, it is simple to use one microprocessor to control many DS18B20s 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.


    • Unique 1-Wire® Interface Requires Only One Port Pin for Communication
    • Reduce Component Count with Integrated Temperature Sensor and EEPROM
    • Measures Temperatures from -55°C to +125°C (-67°F to +257°F)
    • ±0.5°C Accuracy from -10°C to +85°C
    • Programmable Resolution from 9 Bits to 12 Bits
    • No External Components Required
    • Parasitic Power Mode Requires Only 2 Pins for Operation (DQ and GND)
    • Simplifies Distributed Temperature-Sensing Applications with Multidrop Capability
    • Each Device Has a Unique 64-Bit Serial Code Stored in On-Board ROM
    • Flexible User-Definable Nonvolatile (NV) Alarm Settings with Alarm Search Command Identifies Devices with Temperatures Outside Programmed Limits
