Ds18b20 is a one wire digital temperature sensor manufactured by maxim integrated.
Ds18b20 temperature sensor range.
The ds18b20 temperature sensor is also available in waterproof version.
The resolution of the temperature sensor is user configurable to 9 10 11 or 12 bits.
The ds18b20 has an operating temperature range of 55 c to 125 c and the accuracy is 0 5 c over the range of 10 c to 85 c.
Contains ds18b20 temperature sensor.
So you can get temperature from multiple sensors using just one arduino digital pin.
Each ds18b20 temperature sensor has a unique 64 bit serial code.
381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor.
It provides 9 bit to 12 bit celsius temperature readings.
For this sensor we adjusted it into a grove port and had a resistance pre assembled inside so that.
Multiple sensors can share one pin.
The default resolution at power up is 12 bit.
The constriction of the sensor is rugged and also can be purchased with a waterproof option making the mounting process easy.
It can measure temperatures from 55 c to 125 c with 0 5 c accuracy.
Without the external components the unique single bus.
Adafruit industries unique fun diy electronics and kits waterproof ds18b20 digital temperature sensor extras id.
Uses 1 wire interface requires only one digital pin for communication.
This 2m long one wire temperature sensor has a waterproof probe and long wire shape suitable for immersive temperature detection.
It has an operating temperature range of 55 c to 125 c and is accurate to 0 5 c over the range of 10 c to 85 c.
Unique 64 bit id burned into the chip.
It can measure a wide range of temperature from 55 c to 125 with a decent accuracy of 5 c.
The resolution of the tempera ture sensor is user configurable to 9 10 11 or 12 bits corresponding to increments of 0 5 c 0 25 c 0 125 c and 0 0625 c respectively.
Ds18b20 temperature sensor is fairly precise and needs no external components to work.
The chip inside this sensor is ds18b20 which is widely adopted the original one includes three wires inside you need to add an extra resistance to get it working.
While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c.
About ds18b20 sensor the ds18b20 communicates over a 1 wire bus that by definition requires only one data line and ground for communication with arduino.
However the default resolution at power up is 12 bit i e.
This allows you to wire multiple sensors to the same data wire.
