The core functionality of the ds18b20 is its direct to digital temperature sensor.
Adafruit temperature sensor ds18b20.
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.
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.
3846 this is a pre wired and waterproofed version of the ds18b20 sensor made with a ptfe wire cable.

Unlike the ds18b20 this sensor does not come in through hole package so we placed this small sensor on a breakout.
The default resolution at power up is 12 bit.

The adafruit pct2075 temperature sensor is a code compatible drop in replacement for a very common i2c temperature sensor the lm75.
These sensors come in a small three pin package like a transistor and are accurate digital devices.
Adafruit s raspberry pi lesson 11.
They work great with any microcontroller using a single digital pin and you can even connect multiple.
Handy for when you need to measure something far away or in wet conditions.
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.
642 this is a pre wired and waterproofed version of the ds18b20 sensor made with a ptfe wire cable.
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.
Compared to the lm75 however the 11 bit adc in the pct2075 provides more precise measurements when compared to the lm75 s 9 bit adc.

While the sensor is good up to 125 c the cable is jacketed in pvc so we suggest keeping it under 100 deg c.
This i2c digital temperature sensor is one of the more accurate precise we ve ever seen with a typical accuracy of.
Overview the raspbian distribution includes support for the ds18b20 1 wire temperature sensor.
One wire temperature sensors like the ds18b20 are devices that can measure temperature with a minimal amount of hardware and wiring.
