Product Description

Product Description

 

The DS18B20 digital temperature sensor 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 microprocessor. It has an operating temperature range of -55ºC to +125ºC and is accurate to ±0.5ºC over the range of -10ºC to +85ºC.
 

GND is a ground pin.
 

DQ   is 1-Wire Data Bus should be connected to a digital pin on microcontroller.

 

VDD pin supplies power for the sensor which can be between 3.3 to 5V.

 
 

Typical Applications	Features
• Heat systems	• Unique 1-Wire® Interface Requires Only One Port Pin for Communication
• Measuring Instruments	• Measures Temperatures from -55°C to +125°C (-67°F to +257°F)
• Washing machines	• ±0.5°C Accuracy from -10°C to +85°C
• Over-heating protection	• Programmable Resolution from 9 Bits to 12 Bits
	• Each Device Has a Unique 64-Bit Serial Code Stored in On-Board ROM
