642 this is a pre wired and waterproofed version of the ds18b20 sensor made with a ptfe wire cable.
Adafruit temperature sensor ds18b20.
The core functionality of the ds18b20 is its direct to digital temperature sensor.
Handy for when you need to measure something far away or in wet conditions.

This sensor is a little more expensive than the other waterproof version we have with a.
Overview the raspbian distribution includes support for the ds18b20 1 wire temperature sensor.
Unlike the ds18b20 this sensor does not come in through hole package so we placed this small sensor on a breakout.

While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c.
The resolution of the temperature 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.

They work great with any microcontroller using a single digital pin and you can even connect multiple.
These sensors come in a small three pin package like a transistor and are accurate digital devices.
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.
381 this is a pre wired and waterproofed with heat shrink version of the ds18b20 sensor.
Adafruit s raspberry pi lesson 11.
These sensors use a digital protocol to send accurate temperature readings directly to your development board without the need of an analog to digital converter or other extra hardware.
Since the raspberry pi has no adc analog to digital converter it cannot directly use an analog temperature sensor like the tmp36 making the ds18b20 a good choice for temperature sensing.

This i2c digital temperature sensor is one of the more accurate precise we ve ever seen with a typical accuracy of.
The default resolution at power up is 12 bit.
3846 this is a pre wired and waterproofed version of the ds18b20 sensor made with a ptfe wire cable.
One wire temperature sensors like the ds18b20 are devices that can measure temperature with a minimal amount of hardware and wiring.
