Reports degrees c with 9 to 12 bit precision 55c to 125c 0 5c.
Ds18b20 is 1 wire digital temperature sensor from maxim ic.
374 these 1 wire digital temperature sensors are fairly precise 0 5 c over much of the range and can give up to 12 bits of precision from the onboard digital to analog converter.
The ds18b20 communicates over a 1 wire bus that by definition requires only one data line and ground for communication with a central microprocessor.
Each sensor has a unique 64 bit serial number etched into it allows for a huge number of sensors to be used on one data bus.
Gnd is a ground pin.
The ds18b20 temperature sensor is a one wire digital sensor.

Dq is 1 wire data bus should be connected to a digital pin on microcontroller.
The ds18b20 provides 9 to 12 bit configurable temperature readings over a 1 wire interface so that only one wire and ground needs to be connected from a central microprocessor usable with 3 0 5 5v systems.
The ds18b20 communicates over a 1 wire bus that by definition requires only one data line and ground for communication with a central microprocessor.
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 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.
Handy for when you need to measure something far away or in wet conditions.
They work great with any microcontroller using a single digital pin and you can even connect multiple.
You can use one sensor or multiple sensors on the same data line because you can identify each sensor by its unique address.
To use this sensor with the arduino you need the onewire and the dallastemperature libraries.
Reports degrees in celsius with 9 to 12 bit precision from 55 to 125 0 5.
