Description
This is the latest DS18B20 digital temperature sensor from Maxim
IC. Reports degrees C with 9 to 12-bit precision, -55C to 125C
(+/-0.5C). 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. This is a wonderful part that is the corner stone of many
data-logging and temperature control projects.
Structure
DS18B20 is a waterproof temperature sensor packed in a metal and
waterproof housing. For communication with Croduino/Arduino, it
uses only one wire and it is possible to put up to 127 sensors on
one code and measure temperature in 127 different places by using
just one wire!
Features
Ambient temperature range wall mount.
High impact ABS plastic enclosure.
Surface or wall mount.
Available with a Maxim DS18S20
No external power required, or can be optionally powered for faster
operation.
Automatic unique device addressing.
Wide temperature measuring range: -55℃ to +125℃ (-67℉to +257℉)
Adopts ds18b20 temperature sensor chip, high accuracy and sensitive
Each pin of the chip is separated by heat Shrinkable pipe and
sealed by adhesive inside, avoid short circuit and waterproof
Ideal choice for environment, Lab, refrigerator, car, Green house
temperature monitoring
Flexibility resistance, Better thermal conductivity.

This guide explores how to connect a DS18B20 one-wire temperature
sensor to a CircuitPython board and read its temperature from
Python code using a few simple CircuitPython modules.
DS18B20 temperature sensors like the DS18B20 are devices that can
measure temperature with a minimal amount of hardware and wiring.
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. You can get
one-wire sensors in different form factors like waterproof and high
temperature probes--these are perfect for sensing temperature in
many different projects and applications. And since these sensors
use the one-wire protocol you can even have multiple of them
connected to the same pin and read all their temperature values
independently. With just a few connections and some CircuitPython
code you'll be sensing temperature in no time!
