Material List

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!

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!
